It'd be wonderful to have a console code snippet (similar to DTM's "localStorage.setItem('sdsat_stagingLibrary', true)") or even have it added to the Launch Switcher plugin (which currently requires the user navigate to Launch's Environments page). Use case: if we want a third party to be able to test their tag is firing correctly before we publish it.... they don't have access to our launch, nor to our lower environments. in DTM I could just tell them "use this snippet and reload the page", but for Launch, the best I can do is get them to install the Experience Cloud debugger extension (Adobe Experience Cloud Debugger - Chrome Web Store ), tell them to go to "Tools", and manually insert the full embed code I provide them.
I understand the thing that makes this tricky is that folks can have multiple dev environments so the code/extension doesn't always know where to pull dev libraries from... if we'd need to make one as our permanent "for external testing" environment or something (so it'd look more like it did in dtm... launch-ENXXX12345.min.js for prod, launch-ENXXX12345-staging.min.js for staging, and launch-ENXXX12345-dev.min.js as my permanently-easily-accessible-by-console-or-extension dev library), I could work with that. Or if the snippet/extension made me manually input my library ID or something, kinda similar to the Adobe Experience Cloud debugger currently does (but without all the extra bloat of that tool):
