Splitting Multi-Value and Multi-Line field?

I have a list of chrome extensions that are installed that is returned in a multivalue field. One of the results looks like this:

All I really care about is the extension name so I was able to run this query to use rex to extract the names of all the extensions:

index=jamf source=jss_inventory "extensionAttribute.name"="Installed Chrome Extensions & Versions"
| fields extensionAttribute.name, computer_meta.assignedUser
| rex field=extensionAttribute.value max_match=0 "Name: (?<extensions>.*)\n"
| table extensions

This returns:

How can I further extract these extensions in this multi-value field. I can't get mvexpand to work because it says that the new extensions field I created doesn't exist in the data. I can't figure out how to extract each line as a separate result so that I can dedup and get a full list of all installed extensions.

mvexpand should work

index=jamf source=jss_inventory "extensionAttribute.name"="Installed Chrome Extensions & Versions" | fields extensionAttribute.name, computer_meta.assignedUser | rex field=extensionAttribute.value max_match=0 "Name: (?<extensions>.*)\n" | table extensions | mvexpand extensions

Do you get an error?

Alternatively, you could try this

index=jamf source=jss_inventory "extensionAttribute.name"="Installed Chrome Extensions & Versions" | fields extensionAttribute.name, computer_meta.assignedUser | rex field=extensionAttribute.value max_match=0 "Name: (?<extensions>.*)\n" | stats count by extensions | fields - count

The mvexpand doesn't work. No errors, but it doesn't return anything. Your second suggestion inexplicably did work, but I don't understand why.
