Steps to reproduce the issue

The Media Manager is based on vue.js but right now enabling the developer tools is tricky and completely undocumented.
Right now to do so someone has to flip this to false:

But even then there's a message:

Feature flags __VUE_OPTIONS_API__, __VUE_PROD_DEVTOOLS__ are not explicitly defined. You are running the esm-bundler build of Vue, which expects these compile-time feature flags to be globally injected via the bundler config in order to get better tree-shaking in the production bundle.

Expected result

Actual result

System information (as much as possible)

Additional comments

This is probably a placeholder for me, but anyone that wants to step is welcome
