How to send to distribution lists

I’ve just installed emclient 9 and am learning to use it. I’ve searched through the forums and help files and online searches, and everything indicates that I should be able to just type in a distribution list name and it will populate the To: field. My distribution lists all show up in my contacts, imported from Google Workplace contacts. But when I type in the name of a distribution list, or the first part of the name, it doesn’t show the distribution list. And if I enter the full name of the distribution list and tab out of it, nothing happens. Is there a way to do this, or am I missing something?

Any help is much appreciated! Overall I’m super impressed with emclient, but this has me stumped.
