What you describe is a completely different problem which happens to (poorly, inconsistently and costly) happens to sometimes get solved by open office space. Having proper knowledge bases and procedures, including how the ask "the team"/seniors "ad-hoc" questions and get feedback reasonable fast is what you want to have to solve that problems IMHO. Because that also tends to work if e.g. some people are sick or gone (knowledge bases) or can't come to the office (e.g. sick kids at home). Through most important I would say is that communication in remote work is very different to office work and "just throwing slack into the mix" and doing the rest like before isn't going to cut it. And yes that needs proper tooling, too and yes most of the tooling marked for this purpose today is .... pretty bad, sometimes utter garbage creating more work then they save time. Similar the part of procedures is often completely ignored, too.
