Problem joining microsoft teams as a guest with gmail account

[RicardoGG]

Dear community,

I got an invitation to gmail from a University to join a working group in Microsoft teams (see image below). 

My gmail account is linked to my personal Microsoft account. When I click the link "Open Microsoft Teams", I get into my personal Microsoft account (see image below).

However, I don't know what to do after I get here. I've tried different things but I can't get into the Microsoft teams working group of the University as a guest. Could you please help me? Thanks!

@RicardoGG I have guests experiencing a similar issue. Did you ever get this resolved?

@Gabrielleallen No, I couldn't solve it with my gmail email. What I did was using my hotmail email instead. That was the solution I found.
