Wish there was an API endpoint that could allow to retrieve the extension details by its extension number. I am aware there already exists one that allows to retrieve the extension details by its ID.

My concern with the API endpoint above is, the IDs are global, across the tenants. This yields, even setting a certain tenant ID in headers, the API can still locate extension from other tenants as well using the ID provided in URI parameter, which is not ideal.
Also, think of a system where we don’t either have an API endpoint to create extensions, it is likely not realistic to get a track of certain IDs unless you have to go search by yourself and then provide the desired ID as a parameter.
