@baris Thanks! I got one more question about the composer, but I will post in a different topic.
Send hardcoded text as composer textfield data
How can I send a fixed text as if it were what the user would enter in the textfield of the composer?
action:composer.submitand the necessary server side hooks. For example
@baris Could you explain how I can do to send text as if it were the editor so that the composer does not throw error that it enters more than 0 characters?
