Transfer project file from old phone to new phone

I recently upgraded my phone from an s21 to an s25 and im trying to transfer the scans i did with my range on my s21. I did quick share and it sent a zip file to the new phone. I extracted the folder and when trying to open the project files it says there is no compatible apps to open the files. Help please. I have to turn this old phone back in to complete the trade in upgrade.

You need to use computer and transfer all the project folder to it .
There is no phone to phone project transfer options since RevoScan phone app don’t support imports of projects.
