My MacBook Air with Catalina 10.15.7 does not work with the MB16ACE.
My MacBook Air with Mojave does work with teh MB16ACE.
Someone said APPLE does not work with DP Alt Mode. That is not true.
Unfortunately ASUS does not have a driver for their MB16ACE that works with CATALINA 10.15.7.
They do have a driver that works with Catalina 10.15.5.
I downloaded the driver for Catalina 10.14 and got these messages about allow Display Port ....
From ASUS:
"
Driver Package
Version 1.2
2021/02/02 11.6 MBytes
MB Series USB Monitor APP for Mac OS Catalina 10.15.5 (and after, emphasis mine) and Big Sur 11.0
This APP enables you to use ASUS MB series monitor with Mac OS system via USB 3.0 signal.
If your operation system is upgraded to Mac OS 10.15.5 or after, please upgrade and install this APP accordingly. If your operation system is still staying at version before Mac OS 10.15.5, please keep using driver 5.2.1 version.
"
You want the version 1.2 driver for Catalina. (It is for 10.15.5 and after, including Big Sur)
Install it as advised.
Grant access to the app in System Preferences. Quit the app after granting access, then restart it.
It should work now.
If it does not, then best to visit the ASUS support sites for additional help.

Thank you very much because that worked! You are right that the B Series USB Monitor APP for Mac OS Catalina 10.15.5 works for AFTER 10.5.5.
The second step is that the driver is downloaded as DisplayLink Manager and it requires opening system preferences, opening security and privacy and allowing DisplayLink Manager "to record (???) your screen."
In the picture above, it shows DisplayLinkUserAgent which is not the DisplayLink Manager that you need to check and give permission to use. (And you have to unlock and relock in order to save this permission.)
Then a restart and yes, now my ZenScreen MB16ACE will work with my MacBook Air with Catalina 10.15.5.
I called both ASUS and Apple Support and got told they just do not have a driver after 10.15.5
BUT THEY DO.
And another bonus! You can have your MacBook Air monitor, an external monitor in the monitor adaptor slot and the Asus ZenScreen MB16ACE plugged into the USB with USB-C adapter and have all three monitors working independently. WOW!!!!
Thank you for the solution!!!!!
You are welcome.
Glad you got it sorted out. 🙂
