How can I leave or remove a team in Canva?

I have joined too many teams in Canva. It says I cannot remove a team ask admin to remove. In the members tab I cant find any admin of team. Is there anyway I can find admin of team or remove it straight away?

Nope. You need to contact the admin to remove you.

Thats the problem I cant find who is the admin, it wont come in members tab
