I'm at a complete loss on how to set client capabilities. I'm trying to set this one so I can send versioned edits. WorkspaceClientCapabilites.workspaceEdit.documentChanges

My client more or less looks like the one here: https://code.visualstudio.com/docs/extensions/example-language-server
I've spent a few hours search and digging I just can't figure it out.
Non versioned edits work fine using 'changes' instead of 'documentChanges'
I'm about to give up on versioned edits :(

In case it wasn't clear this is for the client portion of a language server im writing for vscode.

Running vscode 1.19.3
Thanks!
