Recommended way to add javascript

there is html embed component and there is project settings

depending on what kind of js you need to add

It would be nice to have something like a stickied header/footer injection in the Navigator for quick access. Like with the head slot.

position: sticky

In my case I'm doing a little calender form like in calendly. For me the ideal would be able to inject an react component inside webstudio. But that is probably too far fetched

Because at the end of the day, injecting vanilla js in a react, doesn't seems to be the optimal way
