Hello Lucid Developers,

I am extending my custom CardIntegration with the ability for users to select assignees.

What I've Achieved So Far:

I can successfully display the current assignee's full name in a User Badge on the card.

My Challenge:

I need to make this User Badge interactive so that a user can click on it and select a different assignee from the available Lucid users. Currently, the field is read-only.

My Research and Proposed Solution:

From my search in the documentation, it seems I need to define the userSearchCallback property for the User Badge. I encountered a roadblock where this property expects a string identifier, not a direct function reference.

My current working hypothesis is to:

1. Implement a callback function that handles the user search logic.

2. Register this function using LucidCardIntegrationRegistry.registerUserSearchCallback(mySearchFunction).

3. Use the string identifier returned by the registration function as the value for the userSearchCallback property.

My Questions:

1. Is this the correct and intended approach for implementing the assignee selection feature?

2. Could you please point me to the specific documentation that details how to integrate an interactive assignee/user search?

3. Are there any example implementations or code snippets available that demonstrate this functionality?

Thank you for your help!
