Elm is lovely, and I'd definitely encourage people to take a look at it from an education point of view at the least. However, I think that's a disingenous comparison.

TypeScript is a superset of JavaScript, which means any JS dev already knows most of TypeScript. They're effectively just learning the type system and best practices on implementing it.

The syntax of Elm is extremely different, which would effectively require developers to learn an entirely new language. It's also a completely different proposition. It's a whole framework, which means complete buy-in on a project. I know there are some interop packages, but you would normally use it instead of React/Vue/Angular etc. This means it's only suitable for new projects.

It's a very nice framework (imo) but it's not a true comparison.

There are not many stories of integrating Elm to existing projects, but there are some. We at Conta AS integrated Elm in our big AngularJS application. So Elm work side by side with AngularJS. It’s possible to embed Elm program to AngularJS code, and it’s possible to embed AngularJS component to Elm program. Which makes the communication part easy. It’s true for any other technology such as React, Vue, etc..
