Accessing Telephoto Lens

What are the possible ways to access Telephoto lens using Camera2 or CameraX api, I've gone through different blogs and forum discussions but couldn't found any solution.

Is there any characteristic or filter available which can be applied on logical camera which in result return telephoto lens access?

No repository file or test is identified in the issue. Start by locating the Camera2 and CameraX samples and checking their camera-selection entry points and relevant API documentation. Done means establishing whether a telephoto lens can be selected through a characteristic or filter, and documenting the supported approach or limitation.
