[INF] Current pdtm version v0.0.5 (latest)
[FTL] Could not run pdtm: [:RUNTIME] Failed to set path: /Users/xxx/.pdtm/go/bin. Add it to $PATH and run again <- [:RUNTIME] add /Users/xxx/.pdtm/go/bin to $PATH env <- shell not supported

current version: v0.0.5
go version: 1.20.2

I tried to add ~/.pdtm/go/bin into the $PATH manual and got the same result:

⋊> ~/g/bin cat ~/.config/fish/conf.d/pdtm.fish
fish_add_path ~/go/bin
fish_add_path ~/.pdtm/go/bin
