Where do your amenities listed come from and if I was a restaurant or hotel owner how could I add or correct mine?

I am making a guide for people who want to better support EV owning visitors and was going to suggest a) that they register their chargers if  they have one via open charge map and b) register their service as an amenity via ABRP... but I realised I don't know how they could!
