Hi @PeKi72 ,
Please try this. Add the email (or name) of the persons you want to send the chat, in an array format like this:

Then add an apply to each, take the outputs from your compose and add the receipt as "Current item" from Dynamic content.
This will iterate through every person in the array and send the message you specify.
So remember [ ] at the start and end, and then " " on each side of each entry and a comma , between all entries but the last.
You can try it with yourself first.
For example
[
"Pekiz@mail.com" ,
"Pekiz@mail.com" ,
"Pekiz@mail.com"
]
