@SpelaU You can’t use a prefilled Airtable form for this without also adding in an Airtable automation and most likely an extra table into your base as well, so that would add a lot of unnecessary clutter/overhead to your base.
If you want to do this with a form, the best way is to use a free Fillout form. Fillout lets you actually update Airtable records from a form, so you can just send them to Fillout for that specific record, and they can approve it there, which automatically updates the record. No extra tables needed, no extra automations needed.
Now that would still end up being 2 or 3 clicks for them, whereas my simple & easy Make webhook option that I mentioned above would only be 1 click for them, and they can do it all from their email. I demonstrate the webhook option on this Airtable podcast episode.
