I have a question about GroupConnect. We followed the documentation and tested in Postman. It seems like we were able to create a package,

https://{{et_subdomain}}.rest.marketingcloudapis.com/ott/v1/registration

then retrieve it,

https://{{et_subdomain}}.rest.marketingcloudapis.com/ott/v1/registration/messenger/2396708113545

then send it.

https://{{et_subdomain}}.rest.marketingcloudapis.com/ott/v1/send

According to what is showing in the documentation, we did everything right based on the responses we got back. But we never received a message in Facebook chat. Maybe we are misunderstanding what this is supposed to do, but are you able to elaborate on this at all? #Mcdeveloper
