Even on the manufacturer's website there are no bags listed as compatible... So I ordered these "Roboparts Dust bag for the Dreame L10s Pro Ultra Heat robot hoover" yesterday.
I received them today and I can confirm that they are compatible. They are a bit smaller than the originals but it will do.

I have the same problem. Galaxus obviously doesn't have the bags for Gen2 in its range at the moment.

Order via Galaxus, Dreame dust bag D10 Plus3x set, Roboparts 6x set or Homava D10 Plus.
There are 3 different models that fit the D10.
