I'm not the one hosting it, another person is. The particular person mentioned we need to make the bot send the files to our own private channel. To do that was needed to it manually ''/usetting'' and then do the steps.
I done all the steps and when, I want to do it the bot only gives me exactly that message. Here's the screenshot: https://i.postimg.cc/zBGdVq2w/Screenshot-1.png
I saw your edit but have no idea where to change that. Got to do it on PC? I’m using iPhone as mobile device.
