So far it was not working, unless I wrongly understood the way of working.
The link led me to a telegram channel, where you can click "start", lanching a conversation with "/start". Nothing happend. Then I tried to launch a picture there. No reaction neither.
So I would be really interested to know if I missed something, I would be happy to adjust this comment to a 5* rate in case it is working for free in the end..
But so far, it is not working from what I saw.
