I added the below lua code to my nvim plugins. I get all the functionality. But when I run :LspRestart I get the message Invalid server name GitHub Copilot.

return {
	"github/copilot.vim",
}

When I inspect :LspInfo, I see:

vim.lsp: Enabled Configurations ~
- ⚠️ WARNING 'GitHub Copilot' config not found. Ensure that vim.lsp.config('GitHub Copilot') was called.
- GitHub Copilot:

I have installed copilot-language-server from Mason. And cannot find anyone else running into this error online :(
