Yes. Featuring is available for both Private and Professional accounts. The principle is the same: you boost your own ad to gain visibility.
Professional sellers who post several ads can boost the ones they want to prioritise, with no obligation to promote them all.
Whatever your status, featuring is paid the same way, via the App Store or Google Play, and an invoice is available for your bookkeeping.
If you sell as a professional, remember to fill in your billing information so your receipts are complete.
