REIT capital gains tax for foreign investors?

I'm a foreign investor and own 900 shares of VICI. Since the company is a REIT, do I have to pay capital gains taxes or anything else (besides the 30% of dividends that are withheld) if I were to sell those shares? I looked FIRPTA up but it's a bit confusing. From what I've gathered since I own less than 5% of a REIT I'm not subject to capital gain taxes, but still, it's always better to be safe than sorry.

I will appreciate it a lot if anyone can clarify this, thanks!
