Is it possible to create Multi-pack bundle using the productVariantRelationshipBulkUpdate mutation?

How do I create Multi-pack bundle using the productVariantRelationshipBulkUpdate mutation? According to the documentation I should be able to create it using this mutation .

But I’m not being able to create one.

Like using this mutation I have to create a new “X” product. Then add components to the “X” product. For simple Fixed bundles this works fine.

Then for a Multi-pack bundle how can I add product “A” in three different quantities like 4, 8 and 12 pack bundle and allow end users(customers) to choose one from the available options? (edited)
