The whole Epic vs Apple was about Apple blocking this. Before being slapped by regulators, Apple had anti-steering policies forbidding iOS apps from even mentioning that purchasing elsewhere is possible.

Even after EU DSA told them to allow purchases via Web, Apple literally demanded a 27% cut from purchases happening outside of App Store (and then a bunch of other arrogantly greedy fee structures that keeps them in courts).

Apple knows how hard is not to be in the duopoly of app stores. They keep web apps half-assed, won't direct users to them, but allow knock-off apps to use your trademarks in their search keywords.
