Is there a way to expose hidden custom REST edpoint for jira cloud app?

[igor.vasiliev]

The problem
In rare occasions Jira Cloud app doesn't hit the /unistalled lifecycle endpoint

Possible solution
Exposing a hidden custom REST endpoint where hidden meaning not shown anywhere in the menu. If it returns 404 then the app is not installed.

Question
Is there a way to expose this custom endpoint which would be requested through the actual app url ie /plugins/servlet/ac/{app-key}/{endpoint-name}

There are no "hidden" REST endpoints.  Your app can expose whatever end point it wants to.
