hreflang tags not visible on google console even tho I put them on page. Why?

Question

I made my website on english language. It has now 1 language en and added the hreflang attributes.

There is no sitemap just the hreflang tags in html.

Most of the online tools see them but Google does not see them - it says in console - "Your site has no hreflang tags."

Website Link

I added hreflangs on all pages.

What am I doing wrong please?

Thanks,

John. V
