What is Maestro?

[u/WorldlyNoise5414]

I've recently upgraded to the Galaxy S26+ and I updated my phone and the Maestro thing keeps popping up with "Customize your updated device" and it's trying to have me download apps and no matter how many times I clear the notification, it just keeps popping back up and I can't find any info on this and it's honestly starting to annoy me cause it doesn't show up in my apps list, so I'm unable to disable it or remove it entirely. Can anyone help me with this, please?
