Stuck in illiquid $14.5/$15 RDW call spread, both legs deep ITM — just let it expire?

Can’t close it, no liquidity, wide bid/ask, can’t get a fill. Stock is at $21.76 so both legs are deep ITM, expires 18 Jun.

Do I just hold to expiry and let Robinhood settle it at max value ($0.50)? Does it happen automatically or do I need to do something?
