So I've been applying potassium permanganate baths (5 seconds in the water, 5 outside of it) and then lathering her with Silver Sulfadiazine (although she wouldn't dry dock for a while and would instead dive in the water) for about a week.
However the white spots which until now looked muted have become more pronounced, the white patch at the margins has turned milky white, and the scute under it has turned pale.

https://i.imgur.com/uE6Gtqc.jpgMy theory is that the potassium permanganate killed one strain of the fungus and so another strain began to dominate instead. However, I am not really knowledgeable in
this topic so I wouldn't know if that is a thing that can happen among funguses.
My reaction so far has been to wash her shell thoroughly using a toothbrush and a very mild soap -In doing so, one of the patches (the one in the middle), reddened underneath, I wonder if there's some sort of inflammation going on, thankfully it quickly went to normal-

Then after drying her I applied a concoction of Neosporin, Clotrimazole, Betametazone and Gentamicin and Silver Sulfadiazine to her shell, particularly to the critical spots and then dry docked her for a couple of hours under a heat lamp and left her in a shallow enclosure with only a little water on one side to sleep in.
I reckon I will be applying this cream and the potassium permanganate baths interchangeably every 2 days, as well as probably rinsing her with iodine. I shall also be looking for several vet opinions (There aren't any herp vets where I live, so I want to see if there will be a consensus)
I will also be changing her water more frequently while this infection lasts and am going to change the filter to a more powerful one.
On the vet's suggestion, in addition to the potassium permanganate solution I also added Omega 6 and 3 to her food, AD3 drops and Calcium, I am also thinking of buying a UV lamp.
Can you give me opinions on the condition of her shell?
What else do you think I should do, any other suggestions?
