Can you add an entry in clients.json?

Maybe update the CHANGELOG as well?

Done, please check.

There is one more issue, i have to (require 'lsp-mint) manually in my own to make those config take effect, but, it seem like some others client will load automatically when lsp is running in mode hook, right?

You have to update lsp-client-packages just like the sample PR I linked.

done, please have a look, thank you.
