I tweaked the meeting template screen to add a button that creates a team's meeting with the following code-
MicrosoftTeams.CreateTeamsMeeting(LookUp(Office365Outlook.CalendarGetTables().value, DisplayName = "Calendar").Name, TextMeetingSubject1.Text, {content: TextMeetingMessage1.Text, contentType: "html"}, "local", Text(DateAdd(DateTimeValue(_selectedMeetingTime.StartTime),-TimeZoneOffset(),Minutes)),Text(DateAdd(DateTimeValue(_selectedMeetingTime.EndTime),-TimeZoneOffset(),Minutes)), true, "teamsForBusiness", Concat(MyPeople,UserPrincipalName&";"), true, true, true);
Error: invalid number of arguments. Not sure what to tweak?
