Do I need to use rel=canonical if the site has multiple languages?

Question

Google

Hello.
I asked this question, there is a site with three languages.
mysite.com/ - Ru version
mysite.com/en/ - English version mysite.com/ua/
- Ukrainian version Are different language versions considered duplicates? Now every page has this code:

<link rel="alternate" hreflang="ru" href="mysite.com" />
<link rel="alternate" hreflang="uk-UA" href="mysite.com/ua" />
<link rel="alternate" hreflang="en" href="mysite.com/en" />
<link rel="canonical" href="mysite.com" />

Links are page-by-page different. What do you think? What do you advise?
Is a canonical needed in this case? Is hreflang configured correctly?
Thanks in advance.

Answer 1

Languages ​​have nothing to do with it. canonical should only be used if the page is being called from multiple locations. For example:
- a page can be opened from two sections
- a page can be opened from a section and a pagination page
Note: If the page can be called from one section and the pagination pages are closed by robots.txt, then canonical is not needed.

Answer 2

No, of course they have different content.
