Bigin follow-up workspace ranked by who is going cold

Build me a follow-up workspace for my book of business in Bigin by Zoho CRM. The Bigin list view never tells me who is going cold, so I want one page I open every morning that ranks the people and companies I own by how long it has been since anyone touched the record, and that lets me act on them without leaving the app.

The main view is a single ranked table of Bigin Contacts and Accounts (Accounts appear as Companies in the Bigin UI). Each row shows the record name, the company it belongs to for contacts, the record owner, the last touch date, and the number of days since last touch, sorted with the most neglected first. Flag anything past the cold threshold visually. Include a search box, a toggle between Contacts, Companies, and both, and an owner filter that defaults to the signed-in user so each rep opens the app and sees their own list, with the option to switch to the whole team.

Last touch is the most recent activity linked to the record across the Calls, Events, Tasks, and Notes modules, whichever is newest. Fetch these in bulk rather than one call per row: pull activity for the whole visible set in batched list reads or COQL select queries and join them to records inside the handler. Bigin rate limits on API credits over a rolling 24 hour window, so per-row fetching on render will exhaust the budget. Cache the computed ranking so the page loads fast, and give me a manual refresh control.

Clicking a row opens a side panel with everything about that record in one place: the contact details (name, title, email, phone, owner, company), the linked company record from the Accounts module, any open deals from the Pipelines module tied to that contact or company with stage and amount, and a reverse chronological activity history that merges calls, events, tasks, and notes.

From that panel I can do three things without switching tools. First, log a call, which creates a record in the Calls module with subject, call type, call start time, and notes. Second, create a follow-up task, which creates a record in the Tasks module with a subject, a due date I pick, and a link back to the contact or company. Third, send a follow-up email through Gmail using the Send a Message operation, where the app drafts a starting message from the recent activity on that record so I am not staring at a blank box, and I can edit the subject and body before it sends. After any of these actions, recalculate that record's last touch so it drops down the list.

I also want to snooze a record for a set number of days so it drops off the list until the snooze expires. Snoozes are per user and stored as app state, never written back to Bigin, so my snoozes never affect a teammate's list. Show snoozed records in a separate tab with the option to unsnooze early. The cold threshold is configurable in a settings area, defaults to 30 days, and is also saved per user.

Bigin technical notes for the handlers: call ${apiDomain}/bigin/v2 with the header Authorization: Zoho-oauthtoken ${accessToken}. The fields query parameter is required on list reads and accepts a maximum of 50 field API names, so discover exact field API names from the fields metadata rather than guessing. Pagination uses page and per_page with per_page capped at 200, switching to page_token beyond 2,000 records. COQL select queries return at most 200 rows per call and 10,000 rows in total. On mutating calls, check the per record code and status values inside the response data array, because a 200 response can still contain per record failures.
