How can I modify the 'order again' button link in a headless shop's customer accounts?

[hanebuechen2000]

I recently introduced new customer accounts to my headless shop. Now I have the problem that when I click on an order in the account and from there click on "order again" I am redirected to my default shopify theme which I am not using. How can I change the link of this button or just disable it?
Thanks for your help.

Hello, this is a screenshot of the page:

 here is the url: https://shopify.com/67453157631/account/orders/5590770680063

If I set up a domain there, will I be able to customize the page? And if yes, where? in my theme editor?

Thank you a lot for your help.
