They could be mealybugs. Are there a white discharges on the branches? Easily removed with cotton buds soaked in isopropyl alcohol. Make sure you check under all the leaves as well as the tops, stems and inside newly growing leaves.

Looks like it got bent or scratched and the plant healed itself. It doesn’t look like pests.

Thank you all! I’ve seen mealy bugs before on other plants, but did not find any on this plant. Thanks again!
