Forge/UI elements inside Custom UI

Is there any way to use Forge/UI elements (eg. Usergroup, User, Userpicker) inside custom UI app ?

Hey @sr48! Thanks for the question. I can see that this is your first time posting in the community so welcome!

Unfortunately, the UI Kit and Custom UI are not cross compatible as the UI Kit uses a custom context environment in which in runs in.

You might find some of the packages available in AtlasKit useful such as Mention and User Picker.

Hope this helps!

Thank You @MatthewFreeman
I will use the Atlaskit package.
