App Store prompts for Microsoft updates. Please help me stop this

I have made every effort to remove Microsoft Office from my M3 MacBook Air including clearing libraries.

The App Store continues to list MS updates.

I confess to having installed Sequoia 15.1 beta. My other computers, without beta software do not offer these updates.

I have just downloaded the general distribution of Sequoia 15.1 which I hoped would fix the problem. It doesn't.

I would appreciate any help please. App Store settings do not help. I cannot delete App Store in order to reinstall it.

Thank you.

Guy
