How to generate Ziggo.nl-cookie.txt

Until last week I used Horizon.tv for the Dutch channels, that worked perfectly.
The EPG was nicely filled and I got a cover (picture) by every broadcast. I could see that file as a cover in Emby.

Because horizon.tv no longer works, I tried kpn.com but I don't get the EPG the way I want it.

I want to use the Ziggo EPG, but I run into a problem. I need a cookie file and I am unable to create it.
I've been trying for a while but I can't make teh cookie file.
Tried with Chrome, Edge, Firefox. When I go to Ziggogo.nl, "Get Cookies" says that there are no cookies for Ziggogo.nl.

In the WebGrab++.config.xml I have included the following line
Nederland 1

I use Windows10, Webgrab++ 3.3 with the 18-10-2022 Epg channels

Webgrab++ I have registered

Who can explain to me how to generate a working Cookie file for ziggo.nl?
