Beginner questions – Ficus lyrata

Hi ! I’m new to this sub and new to taking care of plants.

Surprisingly this Ficus Lyrata survived in my home for 1 1/2 year now.

Except a few brown leaves at the bottom that I cut, I did not do anything.

Should I change the pot for a bigger one ?
I never added something to the soil.
Should I cut some new “heads”?
Now, I’m watering it when I see the top of the soil drying out.

Thank you !
