If you're a Xero customer on a starter, standard or premium plan, you can access their Xero Assistance Programme. This allows you and your team to access free and confidential counselling and support, online or over the phone.
Consider how you can best utilise technology to maintain team communication. Using an application, such as Microsoft Teams or Slack, can encourage your team to regularly communicate. You could also run an automated daily standup within your chosen app or via a third party app, such as Standuply or Standup Alice, which allows you to set questions for your team to answer each day, e.g. how are you feeling, what are you working on, what are your roadblocks, etc.
