How does the seller will know that product stock is low

On Marketplace Multi-Vendor Module for Magento2, there is a setting on the admin end Inventory Settings & Seller Profile Page Settings called “Enable Low Notification".

When this setting is enabled then the seller gets notified through their e-mails when their inventory decreases with subsequent orders. As soon as the inventory reaches the specified minimum level set by the admin, a low stock notification mail will be sent to the seller.  

In the “Low Stock Quantity” setting, the admin will enter low stock quantity, which will allow sending low stock notification mail to sellers when product quantity will be equal to or less than this quantity.
