The range estimate shown on your dash (commonly referred to as the Guess-O-Meter or GOM) will factor in the air temperature and the car's power consumption during the last few trips (measured in kWh/100km for those on the metric system or miles/kWh for those in the U.S.). The power consumption will be affected by your driving conditions and driving style. The GOM was probably pre-loaded with a default value at the factory and is adjusting the estimated range based upon being operated in the real world.
The MINI Cooper SE's GOM is notoriously pessimistic, showing the worst-case scenario. (It's safer to under-promise and over-deliver.) I have seen many reports by people who were able to go further than the estimated range it showed.
If you want a more accurate (less pessimistic) estimate of range, you could calculate it yourself using the average consumption reading and the battery's available capacity of 28.9kWh. Weather, driving style, and elevation changes will impact the real-world range, so remember it is just an estimate.
Cold temperatures in particular will reduce range due to the physics of the battery and the additional energy used to heat the cabin and move through more dense air. As the seasons change and temperatures warm, you should see an increase in the GOM's estimate.
The owner's manual has a chapter dedicated to recommendations for increasing range. Most of those recommendations are similar to those for improving fuel economy in a fossil-fueled car: avoid aggressive starts and stops (where's the fun in that?), be mindful of how you use the climate control, make sure the car is maintained and the tire pressures are correct, etc.
