Damage to tyre flank

Hello, unfortunately something stupid just happened to me. When I parked (really slow), I touched a curb with the left rear wheel. Now there is a notch on the tyre flank (summer tires) with a diameter of approx. 7mm and a depth (at the lowest point) of approx. 4mm. Actually, I only had to change the summer tires for all-year tires in autumn, now I have to prefer this, don’t you think? I can take a few more days with the vehicle. On Thursday I have an appointment in the workshop anyway, in order to repair stonefalls. Here is a photo of the damage. Thank you very much!
