The product feed is generated automatically by our Magento 2 extension via the standard Magento cron.

In case you want to trigger the product feed generation manually, you can execute the following command in the directory of your Magento installation

bin/magento recolize:feed:generate

If you only want to create the product feed for a certain store, you can use the following command:

bin/magento recolize:feed:generate
