How to enable flowbot that created by Power Automate in a private Teams channel.

I am using Power Automate to create a flow to post message to a private Teams channel automatically and periodically, and I am in the channel and I am owner.
When I try to use flowbot as Post identity it failed and return the following error message:
“{"error":{"code":"BotNotInConversationRoster","message":"The bot is not part of the conversation roster."}}”
I use user as Post identity it succeed.
So anybody know if a workaround is available to make flowbot work in a private teams channel?
