83	Can we use a more specific type here?
96–99	If we can't use a more specific type easily, then maybe instead you can add an `invariant` here to make sure that the `messageType` is either one or the other option

83	Invariant can be avoided here and more specific type can be used. However this value is extracted from WebView headers in `landing-handler`. Therefore in order to avoid invariant here we will need to cast from string to `SIWEMEssageType` in `landing-handler`. This casting will have to use `any`. In my opinion it should be safe since in `landing-handler` we will use validator anyway before casting.
96–99	I think the `invariant` you are requesting is already added at line 89.
