Update file input UploaderOptions at runtime (MDB4)

Hi,

is it possible to update the file input UploaderOptions on runtime?

I tried to use the spread operator that works with the datepicker options, but even though the options object is updated, the fileinput adds the files to the queue and not rejects them.

Resources (screenshots, code snippets etc.)

<form>
  <div class="file-field md-form">
    <div mdbBtn color="primary" size="sm" class="waves-light" mdbWavesEffect>
      <span>Choose file</span>
      <input type="file" mdbFileSelect (uploadOutput)="onUploadOutput($event)" [uploadInput]="uploadInput"  [options]="options">
    </div>
    <div class="file-path-wrapper">
      <input class="file-path" type="text" placeholder="Upload your file" [value]="showFiles()">
    </div>
  </div>
  <button mdbBtn color="primary" (click)="startUpload()">Start uploading</button>
</form>

<button type="button" mdbBtn color="primary" mdbWavesEffec (click)="changetype()">Change Type</button>

component:

constructor() {
        this.files = [];
        this.uploadInput = new EventEmitter<UploadInput>();
        this.humanizeBytes = humanizeBytes;
        this.options = {
          concurrency: 1,
          maxUploads: 2,
          allowedContentTypes: ['text/plain', 'image/png']
        };
      }

changetype(){
        this.options.allowedContentTypes = ['video/mp4'];
        this.options = {...this.options}
      }
onUploadOutput(output: UploadOutput | any): void {
        console.log(output)
        if (output.type === 'rejected') {
          this.files =[];
        }
        else if (output.type === 'allAddedToQueue') {
        } else if (output.type === 'addedToQueue') {
          this.files.push(output.file); // add file to array when added
        } else if (output.type === 'uploading') {
          // update current data in files array for uploading file
          const index = this.files.findIndex(file => file.id === output.file.id);
          this.files[index] = output.file;
        } else if (output.type === 'removed') {
          // remove file from array when removed
          this.files = this.files.filter((file: UploadFile) => file !== output.file);
        } else if (output.type === 'dragOver') {
          this.dragOver = true;
        } else if (output.type === 'dragOut') {
        } else if (output.type === 'drop') {
          this.dragOver = false;
        }
        this.showFiles();
      }
