Example: For channel id "UCXuqSBlHAE6Xw-yeJA0Tunw" replace the first two letters "UC" (channel ids always start with "UC") with "UULF". The feed url then looks like this: https://www.youtube.com/feeds/videos.xml?playlist_id=UULFXuq...
It will only contain Videos, no Shorts, but also no Live Streams (in case you want (only) Live Streams use "UULV").
