Typescript viewport event handler does not exist
See original GitHub issueHello, I’m trying to add an event handler to a viewport like so
const viewport = new Viewport().on("clicked", () => {});
But I’m getting the Typescript error Property 'on' does not exist on type 'Viewport'.
Is this method missing from the Viewport’s Typescript definition? Thanks!

Ahh ok so the project was on an older version. It’s now fixed after upgrading from
v5.3.3->v6.2.0. Thanks so much for the help!Turns out the problem was not having
"esModuleInterop": truein my tsconfig.json file. Adding that fixed the type error.
