Why do developers choose Web or Mobile?

We have plans to develop an Android / iPhone compatible app using Jitsi Meet. We plan to use React Native because we have developed React Native apps, but Jitsi Meet is available for both the Web version (that is, React Native uses WebView) and the Mobile version (a component of React Native?) Is it supported? I think we are in a state where either one can be selected, but what kind of guidelines should we use? Could you give me some advice? Thank you.
