Find the people on your Chorus calls who are missing from Salesforce

**Objective:** List the external people who took part in Chorus conversations over the last {lookback-days} days (default 7) and show whether each one exists in Salesforce as a contact, a lead or not at all. If {account-name} is given, only look at that account's conversations.

**Step 1: Collect the conversations in Chorus**

Call `chorus-get-engagements` with date.from = today minus the lookback days and max-records = 100. If {account-name} is not empty, also pass account-name.contains = {account-name}.

**Step 2: Collect the external participants in Chorus**

Call `chorus-get-users` with active = true once, and treat every email it returns as internal. For each conversation from Step 1, call `chorus-get-conversation-participants` with its conversation-id. Keep participants whose email is not internal, and de-duplicate them by email, ignoring case.

**Step 3: Look each person up in Salesforce**

For each external email, call `salesforce-get-contact` with email = that address. If no contact comes back, call `salesforce-get-lead` with email = that address.

**Step 4: Report**

1. **Known contacts:** name, email, Salesforce account, and the Chorus company name. Flag rows where the two company names clearly differ.
2. **Known leads:** name, email, company, lead status, converted.
3. **Not in Salesforce:** email, name, title, company, number of conversations and last conversation date, most conversations first.

Finish by offering to add the people in section 3 as leads, but do not add them.

**Rules & Guidelines:**

* `chorus-get-engagements`, `chorus-get-users` and `chorus-get-conversation-participants` are on the Chorus server. `salesforce-get-contact` and `salesforce-get-lead` are on the Salesforce server.
* This is read-only. Do not call `salesforce-add-lead`, `salesforce-add-contact`, `salesforce-update-contact` or `salesforce-update-lead`.

**Validation:**

* Participants with no email cannot be looked up. Count them and list their names separately.
* If no conversations match, say so and stop.
