How to not ruin the french polish when using a strap?

Hello! I just bought a new guitar (I saved up for a year, as well as waited for a year for it to be built and now I finally have it!) but here's the thing.

I use a strap instead of a footstool, for ergonomic purposes as well as general comfort - the luthier was quite surprised when I asked for a strap button haha

The strap I use is made of leather, this was completely fine with my old guitar which has a hard lacquer, but I used this strap on the new guitar for 10 minutes and I could instantly see some gentle wear around the button. I'm thinking that maybe I should buy a new strap made of some more gentle material such as textiles?

What do you think will solve this issue? Should I just switch back to a footstool or a guitar support instead?
