I am using Dopus v13.11. Currently on the trial period while i migrate my nilesoft shell's config around here.
Regarding adding UWP context menu handler, it doesn't work even without the { }
FileType CONTEXTFORCE CONTEXTMENU=Microsoft.WindowsTerminal_1.21.2911.0_x64__8wekyb3d8bbwe
FileType CONTEXTFORCE CONTEXTMENU=8wekyb3d8bbwe
Since the docs mention about UWP context menu explicitly here, i believe it must have broken sometime later
