This feature is sorely missed in modern. I have over 100 comments on this blog post which walks users through all the options for how this worked under classic.
Most of the comments (from the last couple of years) are frustration around the functionality not being in modern (yet all the configuration options still being there to set it up). Many frustrated users not understanding why the config options don't work. Some comments give detail around the use case of why they are trying to use the feature which you might find valuable to read.
