We should also add a test for this. You'll have to make some updates:

• Update the package.json and server/package.json versions to be 13.0.0-next.2. This is the version your change to @angular/language-service is in
• Update the test application's tsconfig.json to have "strict": true (this took me a while to figure out
• Add a test to ivy_spec.ts

Here's the commit where I finally got this to work: 7ed5d3f. You'll probably want to clean that up a bit more.

vscode-ng-language-service/package.json

"description": "Enable/disable showing completions on potentially undefined values that insert an optional chain call. Requires TS 3.7+ and strict null checks to be enabled."

Requires TS 3.7+ and strict null checks to be enabled. It already adds to the description. I copy this from the extensions of ts in vscode

Yea, I just didn’t expect it to not already be enabled in the test project 😅
