The topic cannot be removed from the schemas channel

Can you please explain what you are trying to do in more detail? And what you have already tried?

I am using different camera sensors, which can be created and deleted by the user at any time. Each camera corresponds to a different topic, so when a user deletes a camera, I want to be able to delete the corresponding topic. Currently, I am using CompressedImageChannel, but it does not provide any interface to delete a topic.
