Make the process of adding third party libs more streamlined for new users
Is your feature request related to a problem? Please describe.
It is usually possible to add third party libraries to observable but the default method proposed in snippets often fails.

Describe the solution you'd like
You already have a solution on observable but I can't imagine it would be easy to find for new users.
Describe alternatives you've considered
If I were a new user to observable and tried installing a third party library and it didn't work I might just give up.
As an example I tried installing @gaearon/lag-radar but accidentally typed require(lag-radar). While the module-require-debugger I linked above says this package is not published on npm the default require just fails with a cryptic error message.
When I tried require(@gaeron/lag-radar) I got another error message. At that point I would probably give up but it turns out you can require @gaeron/lag-radar using skypack. import('https://cdn.skypack.dev/@gaearon/[email protected]?min').
Would be amazing if some of this could be simplified for users since JS developers rely heavily on third party libs for almost everything.
Thanks for this suggestion!
