Humanitarian Map-Layer?

Hi,
thank you for this great plugin.
I would like to use the “humanitarian” Layer. Is there any chance that you could implement this feature in the long run?

And in the meantime: Could you tell me, which js or PHP files I have to edit, in order to get the addon to view humanitarian?
I figured, I would have to change some paths to: https://tile-c.openstreetmap.fr/hot/……png

Is that correct – and can anyone here help me with that?

best regards desputin
