Query Regarding HDFC Credit Card Application

A week ago I applied for a Paytm HDFC credit card. My offer was approved. I did my video KYC. It was in processing state. Today I received an email from HDFC to download a form and to submit that to their physical branch or to post it within 45 days. I am pasting the mail content here. If someone knows what this form is about, please let me know why they are asking to submit it as I have already done my Video KYC.
