ngx-json-viewer' is not a known element: - Angular 12

[fwitkowski]

Angular 12.2.0
"ngx-json-viewer": "3.1.0",

It compiles, but ALS (angular language services) shows error:

'ngx-json-viewer' is not a known element:
1. If 'ngx-json-viewer' is an Angular component, then verify that it is part of this module.
2. If 'ngx-json-viewer' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.ng

@fwitkowski Did you Import NgxJsonViewerModule on your current module?
