Hi, @jatiinyadav, I am not sure , if I am allowed to this, if so may you please help me with this a bit.

Hi @ShrewdLuni,

• The toast message you have added is not visible, make sure that after a successful group creation there is a delay of 1-2 seconds before redirecting to the chat so that the Toast message is visible to the user.
