It is spam. Ignore it.
No matter how advanced the virus/malware/spyware might be, it can't infiltrate iOS/iPadOS devices due to their robust security measures.
iOS / iPadOS devices cannot be infected** with Viruses / Malware / Spyware unless you have intentionally downloaded spurious software or unauthorized apps directly from the internet and installed them on your device or/and have Jailbroken.
**The primary reason for this is Sandboxing. All third-party apps are “sandboxed”, so they are restricted from accessing files stored by other apps or from making changes to the device. Sandboxing is designed to prevent apps from gathering or modifying information stored by other apps.
