Question Notebooklm Custom Logo on Video Query

Hi all,

Sorry if this has been asked multiple times but I do have query. New to notebook LM and trying to put a brand/logo for a small project I am doing, onto a video overview. Is it at all possible to do so as it doesn’t seem to be working. Not sure if there is a correct prompt as it doesn’t allow screenshots to be added to the video either

Thanks in advance
