Auto-detect section page + recordId + schema name in Freedom UI and auto-add a button

Hi ,
I am working on a Freedom UI scenario where I need to perform an action on any record edit page (Contacts, Accounts, Leads, custom objects, etc.).

I need some guidance on how to achieve the following:

1. Detect when a section record page is opened (Freedom UI)
2. Automatically read the current page’s recordId and the entity schema name dynamically
3. Automatically show a button in the Page Toolbar (without manually adding it on every section page)

4. When the user clicks the button, I just need to call a REST service that uses:

    

   /0/rest/UsrMultiFileDownloadService/GetAttachmentsZip?schemaName=<Schema>&recordId=<Id>

5. The requirement is that the user should not write any code and the button should auto-populate for all existing sections that have an attachment detail.

I explored Freedom UI page events, environment context, Remote Modules, and client modules, but I could not find a clear example that lets me get both recordId and schema name dynamically for ANY section (Contacts, Accounts, Leads, custom objects, etc.) or inject a toolbar button programmatically across all pages.

👉 Is there any recommended way in Freedom UI to:

• globally detect the current entity/page context,
• retrieve recordId + schema name,
• and auto-add a custom action/button?

Any examples, API references, or best practices would be very helpful.

Thanks in advance!
