Listen on new emails on a IMAP mailbox

Listen on new emails on a given IMAP mailbox. Converts the binary XML attachment to a stringified xmlproperty on the $data object and converts it to JSON. The Setnode could be replaced with Function nodes for example to do a conversion/mapping/transformation. The JSON is ultimately sent to a HTTP Endpoint via POST. This could be a starter for EDI purposes like receiving or transmitting XML data and conversion via JSON object property mapping.

Help me set up the n8n workflow "Listen on new emails on a IMAP mailbox" (https://n8n.io/workflows/154). It uses: HTTP Request. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
