Sangoma Endpoint Manager Phonebook Directory_Service_URL cisco SPA504G

Hi, I have moved from freepbx to freepbx 13 and I want my Cisco 504G to get the company directory from this URL
On the old freepbx I would go to End Point Configuration Manager>Template Manager and I would modify the file configuration for: spa$mac.xml and type this

<XML_Directory_Service_URL group=“Phone/XML_Service”></XML_Directory_Service_URL>

but on the new freepbx 13 I can’t figure out where I can make this change. I don’t see where the spa$mac.xml file is located

Thank you,
