How to remove Prezi notification from MS Teams

I signed up to prezi video to see what it is and added the app to my microsoft team.
However it is now spamming my account.
I constantly get large posts in my chat saying use us use us. It is really confusing for my students.
How do i stop them spamming me?

Hi @first_last, I am sorry for the inconvenience this might cause you, I’m happy to look into this further.
Could you send me a screenshot of the large post so I can investigate further?

Thanks, @first_last, I’ve forwarded this to our developers. I’ll get back to you as soon as possible.
