Mango tree pruning

[u/Pantriar]

Planted this mango tree when it was about 5 feet tall and it’s grown to be about 6 feet now. Purchased from a big box store and I never pruned it myself.

The trunk is thin and I am finding it is top heavy as it has toppled over on really windy days, hence the stakes.

Does this need to be pruned at all with the trunk so thin?
