I'm writing an interactive chat bot with MS Teams Bot Framework and I'm trying to remove all mentions from the chat message. i.e.
message I'm writing to the bot (inside Team channel with @general mention to push notification):

**"@general @bot hello world"** my code expects only the text message without ANY mentions -> **"hello world".**

My code:

```
async def on_message_activity(self, turn_context: TurnContext):
        user = turn_context.activity.from_property.name
        turn_context.remove_recipient_mention(turn_context.activity)        
        user_input = turn_context.activity.text.strip() 

```

I expect "turn\_context.[remove\_recipient\_mention](https://learn.microsoft.com/en-us/python/api/botbuilder-core/botbuilder.core.turn_context.turncontext?view=botbuilder-py-latest#remove-recipient-mention-activity--botbuilder-schema--models-py3-activity-----str)(turn\_context.activity)" to handle it and remove the recipients from the text message.

It works if I have only the @bot mention but doesn't work when I have multiple mentions in the message.

How can I get rid of all of the mentions from the chat message?
