[naydav]

We should take this data from request

[naydav]

Pls, add declare(strict_types=1); to all of new files
And check code style of all of files

[naydav]

We can use inheritdoc

[naydav]

foreach ($data as $key => $value)

[naydav]

Pls, don't use supertypes only for code reusing (if a relation is not like type A is subtype of B)

[naydav]

Looks like proxy on another method

[naydav]

Looks like resolver should be Magento\\CatalogGraphQl\\Model\\Resolver\\Product\\Related\\RelatedProducts
Why do we need one more layer?
The same for another types of related products
