I want to use ngx-tribute with ngx-quill, but I am facing an issue, selected item (from tribute's dropdown) is not inserting properly. I am attaching two screenshots related to this problem. Am I doing something wrong?

<quill-editor id="quillEditor" [ngxTribute]="options" [(ngModel)]="input" [styles]="{height: '300px'}" #tributeDirective="ngx-tribute"></quill-editor>

options: TributeOptions<TributeValue> = {
    trigger: "@",
    values: [
        { key: 'test1', value: 'test1' },
        { key: 'test2', value: 'test2' },
        { key: 'test3', value: 'test3' }
    ],
    selectTemplate: function (item) {  
      return item.original.key;
    },
   
};
