Lookup an Array Column

I’ve seen this post: https://community.glideapps.com/t/lookup-against-an-array-of-column/3352 but didn’t see an answer? It seems like there should be a simple way to lookup against an array column?

I have three practice groups - each lawyer can have up to three. I need those practice groups to flow through to show up under the firm where the lawyer works. For example, if Susan works at Johnson & Johnson and practices Corporate and Litigation, I need Corporate and Litigation to show up on Johnson & Johnson’s page as an inline list of practice groups. Hope I’m missing something super simple??
