How Do I access the content from Elements after deactivating the theme?

Hello,

For testing purposes, I temporarily deactivated Generatepress and replaced it with the default theme which deleted all of the header elements created in Generatepress. Right now, even when I activate Generatepress again, the elements don't appear and when I go in the backend to edit the elements, I can't find any.

Is there a way to access the elements again after deactivating Generatepress?
