Ionic exclude google photos from camera.PictureSourceType.PHOTOLIBRARY

I'm using ionic 3, I want to select an image from my gallery and crop picture, I've successfully created this, but the problem is when I choose google photos instead of a gallery, the crop editor didn't show up. Therefore I just want to use Gallery option and excluding the google photos option.

        options.sourceType = this.camera.PictureSourceType.PHOTOLIBRARY
        this.camera.getPicture(options).then((imageData) => {  
          this.base64Image = imageData.replace('file://','');
          // for cropping image
          let modal = this.modal.create('CanvaseditPage',{data:"data:image/jpeg;base64," + imageData});
          modal.present();
        }, (err) => {
          console.log(err);
        });

from Ionic exclude google photos from camera.PictureSourceType.PHOTOLIBRARY
