Please guide me to the right site in case this is not the place to submit feature request. I can send meetings from thunderbird, but currently there's no way for those meeting to be recognized from MSTeams. So I have to forcefully send the meeting request from teams. This feature request is meant to add a button (or addon) so meetings sent from Thunderbird can be recognized as MSTeams meetings. Outlook does this with the button shown in the attached image. Apparently, MSTeams already provides APIs to fulfil the desired behaviour. https://docs.microsoft.com/en-us/microsoftteams/platform/apps-in-teams-meetings/api-references?tabs=dotnet
