Help me please to create action button

Hi mates! I’m new to Softr. Please help me to install Add to favourites button as shown on the video Level Up Your Softr No-Code App Build With Action Buttons | Tutorial 2022 - YouTube

My project

This is something that will require heavy use of custom code, so Is not going to be that easy to point you in the right direction. Or at least not before the full set of code is shared by the author of the tutorial.

May be you can post this request in the * Hire a Softr Expert or you can private message me I can take care of this for you.
