Need help with fuse box wiring

[floriddawn]

I have recently purchased the OEM wireless charger (5NA980611A) for my 21 plate AW polo.
I am now wiring the charger to the fuse box and am currently researching the correct fuse slot to plug into.
From the fitting locations document I can see that SC24 in the drivers side fuse box is assigned to both the USB hub in the front storage compartment as well as the wireless charger -R126- as shown below.

I already have SC24 taken up in my fuse box which is what I presume to be the USB C hub already but my question is how can I add the wireless charger to that fuse circuit as well?
I know it is possible to use a fuse tap but I would much rather have an OEM install and plug it in the back.
A picture of my fuse box is shown below.

If I add the wireless charger to that circuit will I then need to install a 7.5 amp fuse?
Many Thanks.
