Page Internal name

I have three languages ​​on my website. How can I create a separate slug for each language page?

It should be linked to language selector on top

How to implement this, please provide instructions
P.S.Thanks in advance

URL slug is generated live from page title in given locale.

When an ad is published, a link is automatically generated under the H1 heading for multiple languages.
When creating a page, a link is not automatically generated under the H1 tag for multiple languages.
When creating a page in three languages, I can enter a single link. I have installed osclass 8.3.1
How can I make a friendly link work in all languages?
The screenshot shows that I've created a link for Russian. How do I add user-friendly links for English and Georgian?

But internal name is not used for link generation, title is.

Yeah, I agree, but only in the ads

but I can't change the link on the page

I can't change it for other languages _ snyat-1-komnatnuyu-kvartiru-v-batumi

The blog plugin also adds only one link for all languages. When an article is available in three languages, having a single link for all languages is incorrect

internal name should not be used to build url.
It's a bug.

If you don't specify an internal name, it won't save the page

You need to define internal name, but it should not be used in url - but it is.
Will be fixed in next osclass versions. Now you cannot change that.
Thanks for feedback!

The blog plugin has the same issue: the link is set up for only one language.

Blog plugin use slug that is static, not language specific
