How does Robinhood Handle Collateral for Synthetic LEAPS/Long Strangles?

I have searched all over the internet and reddit but I can't seem to find a simplified answer. For people who have done PMCC/PMCS on Robinhood, how is collateral handled?

If I buy a LEAPS or a long strangle which would be considered 1 "transaction" on RH, when I go to place a short synthetic covered positions against it, how does Robinhood calculate this? Will it show a defined risk or does it not let you do it because it's naked and is not allowed? I don't want to enter into the long position not knowing how the short position will play out. Yes I have level 3 trading btw. TYIA for anyone who can help me out here.
