ScriptRunner. How to addCustomFieldValue() for IssuePicker with multiple values? What value is expec

Question

I want to update a Issuepicker in a listener. On this page: https://scriptrunner.adaptavist.com/latest/jira/script-fields/issue-picker.html its say do it like this: issueInputParameters.addCustomFieldValue(fieldId, "MSD-5")
This works for one issue to add.
But how to add multiple issues? In the docs of IssueInputParameters its saying:
>> values - the custom field values, must be in the format the field expects. BUT WHAT IS EXPECTED FOR AN ISSUE PICKER? Can somebody help? I want to input a variabel but testet first with static strings.
What doesn't work is: .addCustomFieldValue(fieldId, ["MSD-5", "MSD-6"]) // of course its not a string or .addCustomFieldValue(fieldId, "'MSD-5', 'MSD-6'")

String[] issues = ["MSD-5", "MSD-6"]

.addCustomFieldValue(fieldId,issues)
