How to find the Team ID of an application on Mac

Team ID is a unique identification code given by Apple to a developer inside the Apple ecosystem. It can be used to identify all the applications developed by a particular developer and cannot be altered. You can have multiple applications under the same Team ID.

We can utilize Bundle ID to uniquely identify an application under the same Team ID, which will be unique for a particular application.
