What setup or software do I need to see/ have live access to images as I take them from a DSLR?

Is there a setup that I can have that allows me to have access to the images being taken from a DSLR. That way I can select the one I want and change the name on the spot etc… enter image description here The camera that I’m currently using is a Panasonic Lumix GH5.

Thank you in advance.
