As of GraphQL Admin API version
2022-10, we are releasing a new mutation
This new mutation will allow you to bulk activate or deactivate a single inventory item at many locations, with a maximum of 250 locations at a time.
Instead of having to call inventoryActivate or inventoryDeactivate for each location, you can now do that in bulk for a single inventory item.
