Describe the problem

I am playing with the LS to support multiple running language servers per workspace.

I see the following error:

Panic: unimplemented request: workspace/semanticTokens/refresh

To reproduce

Install the VS Code extension from my fork: https://github.com/kittaakos/vscode-arduino-tools/tree/multi-ls-support/build-artifacts

• Start VS Code,
• Open the sketchbook (assuming it contains more than one sketches) sketch

Expected behavior

It does not throw.

Arduino Language Server version

0.7.1

Arduino CLI version
