Bug? CodemirrorComponent undefined in ts File(Angular 16 with Codemirror 5)

[Lavicola]

Greetings,
I am trying to use the fullScreen Plugin, but I have some troubles.
My Component is:

    <ngx-codemirror #codeMirror
     [(ngModel)]="stream"
      [options]="{
    lineNumbers: true,
    theme: 'material',
    mode: 'text/javascript',
    fullScreen:false,
    EditorConfiguration:true,
    extraKeys: { F11: setFullScreen }
    }"
    ></ngx-codemirror>

In my ts file I want to add the event, however this is always undefined

@ViewChild('codeMirror') codeMirrorCmpt: CodemirrorComponent;
   [....]
  public setFullScreen(){
    
    console.log(this.codeMirrorCmpt)
    this.codeMirrorCmpt.codeMirror?.setOption("fullScreen",true);
    console.log("called")
  }

The other Issue is not helping: #318)

Another Issue (#310) is interesting and I tried it myself:
If I have a button my Component is not undefined, but if I use F11 in my Codeeditor it is again undefined even if I press the Button first and later F11 in my Codeeditor

I randomly got it working, but I still think the solution above should work.

In ts File:

  public closeFullScreen(cm:any) {
    cm.setOption("fullScreen",false);
  }

  public setFullScreen(cm:any){
    cm.setOption("fullScreen",true);
  }

In HTML:
extraKeys: { F11: setFullScreen, Esc: closeFullScreen }
