How can I set Mininmal and Maximal values for input, using ngx-mask and RegExp patterns (for example, I need to set pattern for 0-20 only numbers). Is it possible to do with ngx-mask?

In component.html:

<input
    mask="someMask"
    [patterns]="customPatterns"
>

In component.ts:

class Component {
  customPatterns = {
    // ... some Patterns
  }
}
