The editor is vim, the plugin I use to handle lsp is called coc
If I use the configuration I posted above, I got an error, the coc logs does not look much helpful to me:

Should I reach the coc authors for help?
If I run gleam lsp on the command line I got no output, is that correct?
Then if I press Enter I got this error:
x gleam lsp
error: Fatal compiler bug!
This is a bug in the Gleam compiler, sorry!
