HTML language switcher accessibility

Is there any aria-something or a role to add in a language switch link ? For exemple, I put two links in the footer to change the current language.

<a href="/language/switch/fr">Fr</a>
<a href="/language/switch/uk">Uk</a>

I there any semantic tag to add to this links ?

Example:

<a href="/language/switch/fr" lang="fr" hreflang="fr">Fr</a>

lang attribute doc:

The lang global attribute helps define the language of an element: the language that non-editable elements are written in, or the language that the editable elements should be written in by the user.

hreflang attribute doc:

Hints at the human language of the linked URL. No built-in functionality. Allowed values are the same as the global lang attribute.
