Have a similar issue w/ gleap where using the js code in preloaded will not load the widget, but usage in a custom component is just fine. Downside is its only within the component so formatting around it is not a good experience. Following to see if anyone has suggestions.
As @DannyF mentioned, Retool's Custom Component is the way to embed almost anything we don't have a built-in component for, but there is a trade off. I recommend trying to embed with the IFrame component first.
Dropping the url from the "script.src" on your screenshot may do the trick:
Thanks for the update. I'm sorry we were not able to make it work. Hopefully another user is able to embed a Usersnap widget and can share their experience.
On the other hand, we could create tables and forms for those bugs and feature requests. Then create a query to automatically email them to your admin, It should not take long to implement on Retool.
