Request and Receive Zigbee backup from zigbee2mqtt and save it via SFTP

A single workflow with 2 flows/paths that combine to handle the backup sequence for Zigbee device configuration from HomeAssistant / zigbee2mqtt. This provides a way to automate a periodic capture of Zigbee coordinators and device pairings to speed the recovery process when/if the HomeAssistant instance needs to be rebuilt. Setting up similar automation without n8n (e.g. shell scripts and system timers) is consiterably more challenging. n8n makes it easy and this template should remove any other excuse not to do it. Flow 1 Triggered by Cron/Timer set whatever interval for backups sends mqtt message to request zigbee2mqtt backup (via separate message) Flow 2 Triggered by zigbee2mqtt backup me

Help me set up the n8n workflow "Request and Receive Zigbee backup from zigbee2mqtt and save it via SFTP" (https://n8n.io/workflows/2371). It uses: FTP, MQTT, Code. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
