the plant is very beautiful, maybe the previous owner was not able to take care of it anymore and could not get rid of the white lice, you are very good at taking care of the plant and can get very good results with a mixture of

green soap, denatured spirits, and water, then put it in my plant sprayer

I admire you because you love plants so much and you put them in your room, I have never tried it,
greetings🙏
