Hey @pocaface!
Thanks for requesting the feature.
Looking at our records, I can see we have an open feature request for the functionality you’re after - Delete/remove Member from Group in Google Groups. I am going to let my team know that you were interested in this, too, and in the future should we be able to add this to our app, we will be happy to send you an email.
I will note though that in general, we tend to stay away from Delete Actions.
The reason being that Zapier works well almost all the time, but errors do happen and we'd rather have extra data created than deleted.
You can also follow along on the updates blog where we typically announce features like this: https://zapier.com/zapbook/updates/
While not all feature requests are implemented, customer feedback like this is a huge part of how we continue to grow our platform. If this feature does get developed, we'll reach out to you directly to let you know!
