Jira Automation: Convert string containing user's displayname to a user ID field

[Ryan S]

My JSM project is emailed when a user locks themselves out of their account. The emails that we receive are not customizable, but do contain the user's full display between a set of parentheses exactly as it would appear in Jira products. I need a way to take this display name string and set that user as a requested participant on the ticket.

Here is my attempt at updating the request participants field with this user:

{
"update": {
"Request participants" : [
{
"add": {
"id":"{{issue.description.substringBetween("(",")")}}"
}
}
]
}
}

You can get the Atlassian ID via the search user endpoint, and then use that to set the request participant.
