But it's likely I already agreed to the strings when I agreed to my company's demand that we use Teams.

Bingo. The licenses were agreed to when the product was purchased, not when you click "yes, ok, show me the tutorial"

I mean it sucks and I don't use these tools either despite them being forced into my work machine, but if you're getting psychic damage every morning bc the pop up you could just click through it and ignore the shit tools from there. That's all I'm saying, your sanity is worth clicking a few buttons.
