Feature Request: execute some commands (e.g. find-file, dired) on "main" frame#32

In GitLab by @jeffkowalski on Jun 15, 2022, 22:56 Some eshell commands, like `find-file` and `dired` (and whatever may alias to them), are really meant to execute on the main frame, not the popup equake frame. Consider an alias `alias e 'find-file $1'`. Regrettably, it fires into the equake frame. As well, even hiding the equake frame first still has that effect, as in `alias e '(equake--hide-or-destroy-frame (alist-get (equake--get-monitor) equake--frame)); find-file-other-window $1'`. I'm familiar with find-file-other-frame, but that creates a *new* frame. I would prefer to use an existing one (typically I have only one) --- so let's call it "*the* main one that's not equake". Is there a way to fire some commands targeting "*the* main" frame? Could `display-buffer-use-some-frame` be part of the answer?
