How to set EPG URL to tvheadend?

Help and Support
1

I’m using HTS Tvheadend 4.2.8 bundled with OSMC 2022-03-1
I’ve already configured DVB-T2 channels and their EPG work.
I’ve also configured a first IPTV network there, it works, but I don’t find the configuration place to set an URL of the EPG Sources.

Thank you in advance.
