New Help with Entity Mechanic

I'm trying to make a mechanic for an entity where it will follow a different entity. I tried multiple approaches such as making the entity a creature that is tameable but then I couldn't get the entity to be tamed by the other entity so it could follow it. I tried using custom code snippets using a javascript code generator but it didn't work. Preferably I'd like to program it in using the built in visual scripting rather than custom code. Any help would be appreciated I can also give more info if needed.
