Mobile presets

How do I backup or save purchased LR mobile presets? I am upgrading to iPhone 12 pro max and last time I changed phones I lost all my presets that I had added to mobile app.

I believe you make a Backup of your 'old' phone using iTunes (or iCloud), and then

Restore your data from the backup to the 'new' phone.

I have just 2-days ago, used this procedure (iTunes backup) to transfer all my Apps and data, including Lightroom, from an iPhone-6s to an iPhone-SE.
