Grow lights help. But the one I had survived well until it wasn’t watered during a longer trip with a north facing window in the US south. So it got very little direct light.
Fair enough. Like I said, mine was doing well until a house sitter didn't show up to water it while I was gone. It never quite recovered from that. But it did well for the 2 prior years. Now that I have a house with south facing windows I want to get another one but haven't yet, also the cats my wife wanted have a tendency to eat plants so I'll need a cage for the poor tree or it'll be wrecked.
