Integrating Holiday calendar into Nintex form

Hello Team,

We need your assistance with implementing a validation requirement in SharePoint.

Requirement details:

• We have a Holiday Calendar list in a SharePoint site where holidays are maintained with Start Date, End Date, and Holiday Name.
• There is another SharePoint list called Electronic, which uses an Nintex form
• In the Nintex form, there is a Date field where users select a date.

Expected behavior: When a user selects a date in the InfoPath form:

• The system should validate the selected date against the Holiday Calendar list.
• If the selected date falls on a holiday (between Start Date and End Date), a popup message should appear informing the user that the selected date is a holiday.
