How wet do rubber figs like their soil?

I’ve had this rubber fig since august and the lower stem had a few small leaves but quickly became bare. A few weeks ago I noticed the top leaves drooping and then I wondered….AM I UNDER WATERING.

I got a bit more aggressive with watering and suddenly the lower stems threw out a BUNCH of leaves, so dear plant friends, what is your experience, do rubber figs not like it when their soil completely dries out? Should I try to catch it with a bit of moisture?

Pic is from today with itty bitty lower leaves
