Struggling to Play by Ear - Any Tips?

[Newbie]

Hey everyone, I've been trying to improve my ability to play songs by ear, but I'm finding it pretty challenging. I can usually pick out a melody if I hear it, but translating that to the guitar is another story. I’ve tried a bit of ear training through apps, but I'm not sure if that’s enough. What techniques or methods have you guys found helpful in developing your ear? Do you think actively listening to different genres makes a difference? Any advice or resources would be great!
