Use video chat for meetings (encourage camera on but don't require it - management should lead by example)
Be kind. Reach out using other forms of communication (like snail mail) if you want to encourage each other with thank you notes, etc.
Use some kind of shared wiki for long term 'shared ownership' documentation. Don't be afraid to lead by example. Don't be obtuse. Give visual examples of processes, technical components, etc.
Lean into visual examples everywhere you can (screenshots, mock-ups, diagrams, etc).
In video chat, screen share and encourage use of annotations when discussing things. (Zoom has this feature and it's awesome)
Use an agile cadence. Encourage people to share questions / concerns at story grooming sessions (which should be regular). Also encourage feedback at retrospectives (which should also happen regularly). Managers should lead by example in blameless retrospectives and lean into positive feedback.
If you're a team of all dudes (or any one thing), you have a blindspot with perspective. You should rectify that.
