Hello. I have a IPhone 8 Plus. Is screen monitoring available ?
I hope you're doing well.
For clarification, are you referring to screen mirroring or casting? For Apple devices, screen mirroring is called AirPlay. Check out this link to learn how AirPlay works and its compatibility: How do I use AirPlay and HomeKit with my Roku® streaming device?

All the best,
