Replace shower light with Fan/light Combo

Hello All,
New homeowner here who would greatly appreciate some wiring advice. I'd like to add an exhaust fan to a bathroom that is not currently vented. In the bathroom, there is a vanity light above the sink and a light in the shower. These are controlled by a 3 gang switch in the hall outside the bathroom(3rd switch is for hall light). I would like to replace the light inside the shower with a fan/light combo. I pulled the switch plate off and, from what I can tell, this is the current wiring configuration:

Blue=Neutral
All lights and switches have grounds that are tied into one wire nut.

I purchased a unit that is rated for use above the shower but it needs to be installed on a GFCI circuit. I was thinking I would install a blank GFCI in the bathroom and was hoping that I could get some advice on how my new wiring configuration would look? Thank you in advance for any help and let me know if there is any more information needed!

Welcome to the forums.

First off.... your diagram is in-correct. You have the three neutrals of the lights wirenutted to nothing. Then your incoming neutral is shown supplying hot to the shower and vanity switches.
