This is all getting a bit silly.

If you check back to my original post you will see that I did not ask
about whether I need a license or not.

I DO NOT NEED A LICENSE.

My queries were about the necessity to report the lack of a need for a
license to the authorities and to get some idea of how they behave if
I do nothing.

I would have thought the answer was obvious

There is nothing in law compelling you to tell them that you don't need
a license
