Hi @Anonymous,
In this example you could use a split function to split the two e-mail addresses based on the ; character.
Below is an example:
In this example I am retrieving the second item by using index [1]. The first could be retrieved via [0]
split(triggerOutputs()?['body/ccRecipients'], ';')[1]

However, this expression only works if the CC field always contains 2 email addresses. If you want to get a working expression for only 1 e-mail in CC or even when it is empty it needs to be an expression like below.
In this example I am using an empty to check if it is empty and an indexOf to check if there is a ; character (which means it has at least two e-mail addresses).
if(empty(triggerOutputs()?['body/ccRecipients']), 'Empty', if(equals(indexOf(triggerOutputs()?['body/ccRecipients'], ';'), -1), triggerOutputs()?['body/ccRecipients'], split(triggerOutputs()?['body/ccRecipients'], ';')[1]))
