Hreflang & multiple URL path [closed]

First of all, thank you for your answers, it helped me a lot until now.

However, I can’t find any documentation about this problem: I manage a multilingual blog and the urls of my articles are generated from the title of my articles, some examples below

FR > URL\.fr/la-grande-maison-verte-est-super EN-GB > URL\ 

I had an idea to handle this with href tags in the classic way, like below.

<link rel="alternate" hreflang="en" href="https://URL\.fr/la-grande-maison-verte-est-super" /> <link rel="alternate" hreflang="en-gb" href="https://URL\" /> 

I have some doubts when it comes to the good practice of this method, I do not know if it will impact my SEO that I have text in another language in the URL. Do you have any examples of sites that handle this? I was thinking of a news site but I don’t see any site managing this!
