How do I use advanced field editing to add all request participants from a linked issue?

How do I use this advanced field to copy all request participants from a linked issue. I've figured out this much:

{
"update": {
"Request participants" : [
{
"add": {
"id":"{{xxx}}"
}
}
]
}
}

But cannot figure out what to use for ID in this automation?

You need to use the participant's Atlassian account ID, but this should be possible without having to use the Advanced Field Edit Functionality.

In this example when the rule is manually triggered, it loops over all linked issues (you can further restrict this by link type) and then copies the request participants from the trigger issue's request participants field to each linked issue's request participants field:

The copy functionality in edit issue is hidden behind the ... menu:

Awesome! That was the missing link, thank you so much @Nicolas Brunson !
