Configuration of a website with Typo3 v12.4.17 and SEO optimisation -- 3

We run a website with Typo3 v12.4.17. The website is based on the preconfigured distribution: pizpalue_distribution (https://extensions.typo3.org/extension/pizpalue_distribution). The website was created by us in two languages (German and English). Now the SEO optimisation is to be carried out using the TYPO3 CMS SEO extension (https://packagist.org/packages/typo3/cms-seo). For example, the sitemaps.xml must be created and updated. The robots.txt must also be created.

I have noticed the following issues:

1)
SEO is missing in Typo3 Backend menu

2)
https://www.XXX.com/sitemap.xml covers only 7 URLs, however the Website has several more pages, which should be listed in the sitemap.xml

In the end, all German pages should be listed under: https://www.XXX.com/sitemap.xml

3)
German version: https://www.XXX.com/?1533906435 is not available

4)
English version: https://www.XXX.com/en/?1533906435 is not available

5)
https://www.XXX.com/en/sitemap.xml is not available

In the end, all English pages should be listed under: https://www.XXX.com/en/sitemap.xml

We are looking for a Typo3 expert who can check the extension configuration and also carry out the SEO optimisation.
