Safari browser – Datepicker not working

Hi,

I am using this plugin and created a custom field in the checkout page, which has datepicker function to enter the date of birth.

In safari browsers the datepicker is not working.
I have attached the screenshots for the same.

Chrome: https://snipboard.io/8NX5hI.jpg – It works fine
Safari: https://snipboard.io/57EHe8.jpg – Empty field

Please help me to fix the issue.
Thanks in advance.
