Is there any way to run "shopify app dev" without tunnel?

Hey everyone!

When developing my theme extension locally, I want the CLI to push the changes to shopify. This works with “shopify app dev”, but only if I have a tunnel configured. I don’t see why I need one for a theme extension. The files are pushed directly to shopify, correct? Can I somehow run the command without a tunnel?

(I know that “shopify app deloy” works without a tunnel, but then I need to run this manually every time I want to test my changes)

Thanks for any help!
