How can I host my Netlify code on a Shopify domain?

[fabcodeuser5]

My website is made in Shopify Liquid theme and is hosted and managed by Shopify. I have designed new website in React Gatsby and hosted it on Netlify. Now I want to host my Netlify code on my Shopify hosted domain. I have added required DNS to Netlify and added its nameservers to Shopify. Our new website was shown for few minutes and then reverted back to old Shopify website.

Please help me with this as I'm new to hosting. It is quite urgent.

I'll be very thankful to you...

I have added required DNS and nameservers but not working fine. I want my new Netlify code to be hosted on Shopify hosted Domain.
