Restore defaults on draw.io app

Hello everyone!

** Is it possible to restore all settings to their default values?**

I can’t seem to find this option, but I would like to reset everything, as I want to adjust the resolution settings (to maximum or custom resolution) when importing new photos.

Additionally, is there a way to set a custom scaling option for photos?
Sometimes the original size is too large, but the automatically scaled version ends up being too small and unclear. Ideally, I would like to import photos at the highest possible resolution.

Thank you in advance!
