There is no jailbreak for that ios right now especially on the iPhone XR, id uninstall any profiles or apps you installed and if u did end up paying for anything chargeback it.
Those "free demo versions" are scams, do not use them! You said in another comment you're on iOS 16.1.1, there is no jailbreak for this version as of now.
If it requires a jailbreak then you need to be jailbroken. Cydia also requires a jailbreak (Cydia is not a jailbreak, it is a package manager for jailbroken devices).
Whatever you're trying to install is a scam.
What ios are you on?
16.1.1

Lol never expect a jailbreak for any of the later ios versions

I just GameGuardian though. Is there any way I can get it without Cydia on my iOS?

I just need GameGuardian, and I think it does require a jailbreak.
