How to make the Description field mandatory and rename it in the Platform Analytics "Create New Dash

[Snow Developr12]

Hi Team,

I'm working with Platform Analytics Workspace in ServiceNow.

When I click Create New Dashboard, a modal dialog opens with the following fields:

Dashboard Name (mandatory)
Description (optional)

I have the following requirements:

Rename the Description field label to a custom label.
Make the Description field mandatory before the dashboard can be created.

I've looked through UI Builder and the workspace configuration but couldn't find where this dialog is configured. It appears to be an out-of-the-box modal.

Could anyone help with the following questions?

Which UI Builder page or UX component is responsible for rendering this dialog?
Is this modal configurable, or is it hardcoded in the Platform Analytics application?
Is there a supported way to rename the Description field and make it mandatory without modifying OOB components?

Any guidance would be greatly appreciated.

Thank you!
