Share user and script over Google Assistant / Home

Hello world,
I have followed step by step the guide of Google Assitant integration.

But when I try to share the project with my wife I can’t find it on the Google Assistant of her.
The only step that I can’t understand is in this point


“Copy and share the link”… I can’t find any link to share, only a checkbox on the user creation.
Anyone have shared with success? Can you help me?
