Guys,
Is there any other communication channel for Esenthel communication instead of this forum ?

It would be nice if there is one,

This is the only official one

There was a Discord channel operational a few years back, not sure how active it is though.

Link to Discord thread

The Discord server is up and running. Usually, there is no activity whatsoever, until someone joins and asks a question. As far as I can tell, all questions get answered.

I've created an official Discord channel if anyone's interested
