Question about backing up Procreate

For a long time I believed that my Procreate docs weren’t being backed up when my iPad backed up every night. My logic was, if I went into iCloud, I didn’t see any files representing ProCreate documents. However, I noticed recently that ProCreate itself represents a huge percentage of the data saved in my iCloud. So, if my iPad were to crash and I restored ProCreate from the backup, would all of my procreate art be restored as well?
