Twitch App TV for webOS 5
Ok, my Smart TV is a colombian local branded TV but it has webOS 5.4. Basically it is a LG SmartTV because of the model but the branding is 100% from Colombia. My TV is a Challenger with model UHD50LWSMARTBT.
In the LG Content Store, I found the Twitch app: https://co.lgappstv.com/main/tvapp/detail?appId=1004947&catCode1=&moreYn=Y&cateYn=N&orderType=4&headerName=Todas&appRankCode=1&sellrUsrNo=&curPage=2
Unfortunately, this app is not available for Colombia because in my TV I am unable to find it. It's amazing I can find in the store the TikTok app but not the Twitch app... So, my suggestion is to enable the Twitch app TV for Colombia or at least for webOS 5.
