Angular startup project licence problem

Hello,
I want to use your gojs-angular-basic project and added my licence key but not working.

I used in constructor, ng on init but not working. I guess, problem will be with angular, but it is not.
How can i use it?

Thanks

“angular”: “13.0.0”
“gojs”: “^2.1.54”,
“gojs-angular”: “^2.0.4”,
