URL I don’t want in my site map

Hi,
I’m now using your plugin and I love it.
I have issues with the site map.
Here is the link :https://www.banahan.fr/sitemap_index.xml
I’m getting entry that I don’t want
exemple :
https://www.banahan.fr/slideshow-sitemap.xml
https://www.banahan.fr/testimonial-sitemap.xml
and all the testimonial inside

I have already added this to my function.php
/**
* Filter URL entry before it gets added to the sitemap.
*
* @param array $url Array of URL parts.
* @param string $type URL type. Can be user, post or term.
* @param object $object Data object for the URL.
*/
add_filter( ‘rank_math/sitemap/entry’, function( $url, $type, $object ){
return $url;
}, 10, 3 );

But I can;’t figure how to remove the other links.
Thanks for helping
