Download of Invoice PDF

Hi all,

is there an Endpoint we could use to download the PDF of an invoice created in Event Temple?

We saw that you use an API-Call to another API /restpack.io/api/html2pdf/v7/convert?access_token="" to achive this over the UI. But i think we can't use this call because we don't know how to genrate the acces token for that call.

Best regards,
