It's very kind of you to look this up in a manual that doesn't even apply
to your camera!
I had read those pages pretty carefully before posting about it and I can
only make out that Focus Bracketing is for flash, with a special processing
method in OMW, and Focus Stacking the only capability that relates to the
subject we're talking about. Since "Focus Stacking" is an option under the
"Bracketing" menu, this is fairly confusing. It's no wonder that the OM-1
menus might have been improved in this area. Frankly, I think the manual
is a bit garbled and it doesn't help mixing flash into the subject. The
only inference about flash in the menus is where you can select a recharge
interval.
It is evident to me that Bracketing is necessary for the Stacking process,
but there aren't identical. However, I think the only way to get a set of
brackets is to let the camera run through the whole FS process, which is
Brackets + Stack image creation. All the brackets are on the card and that
last image is the stacked one. Throw it away if you want to roll your
own. You now have the brackets to do whatever you want.
This article seems to support my take:
https://learnandsupport.getolympus.com/learn-center/photography-tips/macro/autumn-mushrooms-focus-stacking-bracketing
For lenses that aren't compatible with FS?
The FS option is greyed out in the menu when a non-compatible lens is
attached. Probably true of your camera too.

I've come to the same conclusion. I believe it would be useful for me with
a longer macro, 45mm or longer, a super tele, and a particular mind-set. I
have made some photos with the DZ 50/2 macro, and I might have gotten some
better backgrounds by a smidge, but I accept the compromise. The mZ 60/2.8
seems like an exciting lens, second on my short list at the moment.
It is scarcely believable that a useful bracket set can be made without
using a tripod, especially with a tele as long as 100-400. Just amazing.
