MS Teams Webhook problem

Hello!

We have a problem with Teams webhooks. We lost part of log when we send a webhook from Azure Data Explorer via MS Flow or from Elastic.

For example:

Full log - "ASA: Group <groupname> User <user> IP <ip> assigned to session".

And in Teams it looks like - "ASA: Group User <user> IP <ip> assigned to session". (without <groupname>).

Any solutions?

Thanks! Regards, Nikita Larin.
