I thought this would be easier than it's turned out to be. There are

nothing recent - including a 5 year old Ubuntu post saying it works.
Other wifi devices seem to be recognized out of the box or with a
simple install of non-free firmware but not this one - at least not
in Bullseye or Bookworm.
The adapter itself seems to be quite popular so I'm hoping someone
can provide some clues on how to make it work
Thanks.
Your device should be based on "RTL8822B" chip from Realtek, so you
need to install "firmware-realtek" package.
If after doing that you still didn't get a functioning network wifi
adapter you might need to build driver kernel module. [1]
This is what I had to do to get USB Bluetooth adapter from Asus to
work without issues, even though it is supported by kernel in "bullseye".
It is always the best to include extra information about your setup
when you asking for help.
At least output from these commands would be a start:
$ uname -a
$ lsusb -v -t
# journalctl -b 0 --no-pager | grep -iE "rtl|rtk_|firmware"
If the output is long you can use "paste" service [2] and send us a link.

Thanks Alexander, but installing firmware-realtek doesn't work. It was
the first thing I tried. Secondly, the ASUS driver fails to compile
under Bullseye & later. It throws an error:
1.5_33902.20190604_COEX20180928-6a6a/include/rtw_security.h:255:8:
error: redefinition of ‘struct sha256_state’
255 | struct sha256_state {
| ^~~~~~~~~~~~
This is the same error I find in various drivers from GitHub. They all
seem to be for older kernels and no longer compile. The fact that
drivers have existed for so long was one reason I thought the device
should be reasonably supported by now.
I had considered posting the output of lsusb but it simply shows that
the device is recognized. Making it verbose returns a lot of
capabilities information but not much else. Here it is:

The journalctl command returns nothing.
Found a github repository that compiles on Bullseye at
https://github.com/morrownr/88x2bu. Then it's a matter of doing the
following as root
git clone https://github.com/morrownr/88x2bu
cd 88x2bu-20210702 ## date string may different
make clean
make
make install
then rebooting. The wifi dongle now shows in "ip addr".
