Photoshop on Web: Copy objects or layers from one file (project) to another

I am trying to copy a piece of text that's in its own layer from one file/project to another. I have tried copy/paste on the text itself and copy/paste on the layer, but nothing. If this is not possible, is there any other way to use content from one file in another? 

This is Photoshop on Web, using the Chrome browser. Thank you in advance.
