I think the healthier way to handle that is to explain why it’s a good thing and help them set appropriate boundaries. I like what my boss does, every week or two they have a “no tech” day where they put their phones in a safe, including the parents. They then have fun together, either by playing board games, having a picnic, etc.

Give them advance notice so they can plan appropriately, and make sure it’s fun. If they like it, they’ll likely want to do it again.
