You are using the angular material components in your code afaik.

So you first need to install the @angular/material libary:

   npm i @angular/material

After installing you just import the needed component modules in your ngModule:

    import {MatTooltipModule} from '@angular/material/tooltip';
    
   @ngModule({
        imports: [..., MatTooltipModule]
     })

To get started with angular/material:

The above answer is perfectly alright but to add some more information,

If you are using modular approach then you might need to import it into your current module too.

enter image description here

As in my case from the above image. I need to import it into my "setting-manager.module.ts"

import {MatTooltipModule} from '@angular/material/tooltip';
@ngModule({
    imports: [MatTooltipModule]
})
