Is there a way to initiate a deep link to a call just as in chat : https://teams.microsoft.com/l/chat/0/0?users= I am trying to add a button to adaptive card that initiates a call between 2 users on Microsoft Teams. I tried callto: [email address] but the link shows me : "
Due to an internal error, this web page could not be loaded. We recommend that you close this page.
" even though if I type the link directly to search bar in chrome, it redirects to starting a call in teams. but clicking on the ActionOpenURL button gives me the prev error. So I have 2 questions for now: is there a possible way to initiate a call link between 2 users and if not, how can I solve the callto problem?
