I think that this is something senior devs/admins need to try and influence. I've made it a goal to actively mentor the less experienced on my team (and even some senior admins) during COVID. Sometimes I phrase this as "Check out this stupid thing I did." That lowers everyone's guard, and then you can explain how you solved an issue, or how you dealt with a stakeholder in a professional manner. If us senior folks want to have WFH, then we have an obligation to other employees to help them adjust and learn.
