Read More support

Hey guys, can this be done in Elementor? I tried but could not get it done and not seeing any instructions on the net for this. Only thing I am seeing is html instructions here:

If it cannot be done in Elementor, can anyone give me a general code to use in Additional CSS please so I will be able to add the Read More on any page on my site? Thanks.
