Not receiving push notifications from Retool app as I previously declined Notifications in settings

The Retool Support Team received this question, and we want to make sure other builders can see the response too:
When opening my Retool app on mobile (iPhone) for the first time I declined and did not allow mobile notifications to be sent to me.
I am now trying out the Retool push notifications tool and cannot amend my notifications settings for the Retool app retrospectively - hence I don't receive any push notifications.
How can I ensure I see mobile notifications going forward?

Delete the app and reinstall on your phone. Allow notifications when prompted and you will be all set.
