Instagram &__a=1 is not working now because of CORS issue in my website. How can I access this

I have a website https://www.loadbase.tech but when I search for instagram video download for URL https://www.instagram.com/p/CIdPA_pgIU-/?igshid=xp7b6x4320y6 its not working. I have Javascript code for concat the url with &__a=1 so that URL will become https://www.instagram.com/p/CIdPA_pgIU-/?igshid=xp7b6x4320y6&__a=1. So that I can get the video root URL easily. It was working but now Its giving CORS issue. Please help me on this.
