Just to elaborate: After

  (setq frame (window-frame))
  (make-frame)

a plain

  (make-frame-visible frame)

indeed won't change anything.  But

  (setq frame (window-frame))
  (make-frame)
  (iconify-frame frame)

followed by

  (make-frame-visible frame)

usually will shift focus to the frame.  Conceptually,

  (set-frame-parameter frame 'no-focus-on-map t)

should fix it but here on Debian Buster this does not work and I have to
use

  (set-frame-parameter frame 'no-accept-focus t))

to handle Lennart's use case.  This is not TRT because the frame
probably should accept focus later but so far I have not found a
reliable way to fix that.
