hey all, i’m working on a coc.nvim plugin for vim/neovim, and coc.nvim is built on vscode’s plugin system, so there’s a lot of potential overlap. at the moment i’m working on getting the signature help support working. i’ve followed calva’s code initialization code into main.ts and signature.ts, and have mirrored it in my project. in addition to the vscode.languages.registerSignatureHelpProvider call in src/extensions.ts, is there anything else that’s needed to make signature help provider stuff work?
