How to copy/export kdbx files from the authpasscloud to my local device?

Hi there, I wonder how to export my cloud kdbx files onto my local device? I created several folders full of files in the cloud. Now it would be very complex to create the same again on my device. It would feel more safe for me to have it all not only in the cloud.
Is there a way to copy or export? Thank you very much for your help!
Best regards!
