It's pretty dam close to native. I would consider researching it again. You could do away with Electron altogether and just run it in browser. You can make it a PWA to give it that "Native app" feel so the users are none the wiser but you don't have to deal with the complexities of Electron and managing releases etc. If you want to launch a new release just deploy it to your web host and you're done for all platforms.

This is all assuming there isn't some specific OS level requirements in your app. I know there are other video editors using WASM successfully and apps like Figma.
