Create opportunities for socialization.

You have some great platforms for collaboration, right? Use them to create opportunities for your team to socialize with each other. There are a lot of formats this can take: posing icebreaker questions in a synchronous setting or creating a dedicated channel aligned to hobbies in an asynchronous setting. Frame the session so people know what to expect. The simplest recipe for a socially-oriented meeting is this: no shop talk, have fun!
