My team found in https://docs.microsoft.com/en-us/microsoftteams/platform/bots/how-to/conversations/send-proactive-me... how to send messages via a bot that show up under the left side “Chat” section without trouble. However when trying to send to a tab in the “Teams” section it returns the error “The bot is not part of the conversation roster”. How does one go about doing this without special admin permissions or using the Graph API?
