How to make fields mandatory in assistant using page designer

Hello Team,

@IFS Community , 

How do we make a field in a assistant using page designer?

I can only see the field in RED colour but the validation isnt being added and the user can skip without entering a value? Is there a solution for this

I am looking this in 23R2 version 

Please do let me know if this can be done through configurations. Thank you

Regards,

Rakesh
