Does gocov not support generics in Go version 1.20?

[FanLu1994]

I'm using go build cover with Go version 1.20, and then generating an old version coverage report using go tool covdata textfmt -i . -o result.txt. However, when I tried to convert the report using gocov, I encountered an error. Does gocov not support generics in Go version 1.20?
error

 expected '(', found '[' (and 5 more errors)

Type parameters should be supported with #91. I haven't used covdata, so I don't know if there's something special about it that is stopping things from working.
