Mbsc-calendar readonly property seems not working

When using mbsc-calendar with ionic as a directive, set readonly property to true will not prevent the calendar to popup, and the calendar is selectabe.
I tried:
<ion-input mbsc-calendar [readonly]="true"></ion-input>
<ion-input mbsc-calendar [readOnly]="true"></ion-input>
<ion-input mbsc-calendar [mbsc-options]="settings"></ion-input>
const settings:MbscCalendarOptions = {readOnly: true}
const settings:MbscCalendarOptions = {readonly: true}

The problem is that the “readonly” settings is missing from the Calendar types.
You can still use it inside the settings, but you will need to declare it as any, also, make sure you declare the settings inside your component (you cannot do that using const):

  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
export class HomePage {
  settings: any = {
    readonly: true

However, please note that the readonly setting will not prevent opening the calendar, only it won’t let picking a value. To prevent the opening as well, you can use the disabled option.
