First time fiddle leaf fig owner help

Hi everyone☺️ this is my first time caring for a fiddle leaf fig and I’m very excited! She’s leaning a lot and I’m a bit concerned it’ll tip over. It came to us in a 10” plastic planter. We put it on a plastic tray with wheels. We’re going to shop for a heavier planter today (ceramic?) and possibly a stake to help her stay upright. Does anyone have any suggestions for how to help her stay upright? I will of course ask at the nursery today, too, but thought I throw my question out to the pros (that’s you guys🙃.) I want to do this beaut of a tree right 🥲
