After searching a lot, I found the solution, I had to have the following urlset:
I think it’s an assumption to say that just because a page shows up in Google search that Google has actually indexed it. Especially if you’re just using a search like site:example.com. If key word searches return your page then it’s probably safe to assume it’s indexed. It’s also possible that Google makes several iterations indexing a page before Google ...
Have you looked at the Status column? It should show "Success" if Google reads it correctly as well as the last date Google read your sitemap.
Just as an FYI, there's lots of comments here regarding the Sitemap Paradox. It might be beneficial for you to read through that discussion.
The answers are all here:
Tell Google about localized versions of your page
Two of the most important key points to note are:
Each language version must list itself as well as all other language versions.

For inspect information, try this.
If you site was not crawl yet, you may try to re index your page ...
Google crawls pages on it's own schedule. A new site probably has a lower priority than an already existing site with lots of existing traffic. You might want to simply submit a few individual pages to Google Search Console via Inspect URL.
My experience is that it takes about 7-10 days from submitting them via GSC for them to affect the number of pages ...
Yes, it is normal. Because if you create a sitemap tree, you should make the sitemap on the top level as Sitemap Index, which contains all other nested sitemaps. The markup of sitemap index is different then of single sitemap. Look:
Sitemap Index (contains sitemaps!)
<?xml version="1.0" encoding="UTF-8"?>
It isn't normal - GSC should be showing the total number of discovered URLs found next to this parent sitemap, and once you click on it, then it should show each individual sitemap with their respective URLs found.
My guess is that there's something wrong with this parent sitemap file - have you tested using online tools? How about using the "live test" ...
