Custom field in the attendees block

[m.poliit]

How to change the participants block, I have a custom field in the Contact entity, namely "external id". I want to display this field in the "participants" block, something like Name (external id) -> phone number.

How can I do this?

I found that this block is generated in this file client/modules/crm/src/views/call/fields/contacts.js but how to add my custom field to name, I can't solve. Thanks
