Bot only responds to livechat when outgoing webhook channel is set to all_private_groups

Description

Currently I am trying to setup Livechat with a RASA Chatbot and Rocket Chat Realtime API.
My problem right now is that my bot only responds to the user in a livechat room when i set the channel of the bot’s outgoing webhook to all_private_groups.

When I transfer the chat from the bot to a human livechat agent, the bot leaves the livechat room but is still capable of sending messages into the livechat room.
I did configure my rocketchat instance with the environmental variables (RESPOND_TO_LIVECHAT, etc.).

Am I missing something? Thanks in advance

Any additional Information

Has anyone an idea, why it only works when the outgoing webhook is set to all_private_groups? Because of that the bot receives unwanted messages of private groups which it is not part of.
