Help with setting up an international version of my store

Hi!

I’m a. bot lost trying to implement hreflang tags

I was following this article: https://www.semrush.com/blog/7-common-hreflang-mistakes-and-how-to-fix-them/

I see that these tags are used when there is a variation in the language between the two sites

The two of my sites are more or less identical. Also the language used in both the sites is the same.

In this case how do i successfully implement hreflang tags?

Is this the correct way to use them in the theme.liquid section of both my stores?

Really appreciate the guidance
