Move tiles to group

Phaser 3
1

Is it possible to move tiles to group and then use it as a normal spites with body and physics (not tiles) ?
I try this but it doesn’t work :

   var map = this.make.tilemap({ key: 'map'});   
   var tileset = map.addTilesetImage('pesok_frames', 'tiles');  
   var pesok_layer = map.createDynamicLayer('my_layer', tileset);    

    var group_pesok = this.physics.add.group(pesok_layer);

// It shows wrong number :
   num_text = this.add.text(50, 530, 'Num of elements in group : ' + group_pesok.getLength() );
