Using Deep link in Mobile App with Free Plan (without native Push notification)

I would like to open the Retool app in iOS and be able to control the app, views, and other actions to open specific pages of my app from an external link. For example, clicking on a button or Email link.

I just was able to use<> to open the Retool app but not able to select the app and any view or anything else.

Due to using the Free Plan, I'm not able to use the Native Push notification feature or use web mode.

Could you please helm me find the correct way to deep linking in the mobile app in the free plan?
