I’m not sure you’re picking up what I’m putting down.
You cannot do what you’re trying to do. I don’t know why. Other people can. I can. You can’t. There could be a lot of reasons for that and you’re failing to troubleshoot the problem. None of that is an indictment of you.
Try to do something else: open a container tab (I am a firefox user, so I use Firefox’s container tabs), log into google and watch your videos. Open up a different container tab (again, I am a Firefox user so I have to make a different container to use) and see if the recommendations follow you there.
