I found the following information in various articles on the internet:
The DJI Mini 3 Pro has a CE marking, but does not yet have a class marking. This is still available on very few drones. Since only the class marking is missing and the drone is under 250g, the following BAZEL regulations currently apply:

Drones without class markings can be flown according to the rules of the transition category, which will gradually become more restrictive:
Until December 2023
Weight Certificate Operation as per Additional Operating Restrictions.
<250g Not required A1 None
From January 2024
Weight Certificate Operation according to Additional Operating Restrictions
<250g Not required A1 None
Based on the various information found on the internet, I assume that if you have a drone in the <250g category, you will not be affected by more restrictive regulations in the foreseeable future.
