On Mac OS 10 - Change BACKUP path

LibreOffice on an iMac with OC 10.15.7
I would like to change the Path for Backup.
It is now /Users/my name/Library/Application Support/LibreOffice/4/user/backup
I would like to change the Path to /users/my name/Documents/Backup

At Preferences>LibreOffice>Paths>Backups, I have selected the backup path (/Users/my name/Library/Application Support/LibreOffice/4/user/backup) and then clicked on Edit, but that simply opens the “backup” folder. As best I can tell, it does not offer an opportunity to change the path to the backup folder.
