@titusroz03 have you configured cts authorization <methodlistname> list cts command?
aaa authorization network CTS group ISE_RADIUScts authorization list CTS
Here is a working example
@nhassiotis78 you don't have a 9300 hardware appliance. The ASA software image you used upgrades the ASA software to 9.16.4 and the hardware firmware, which is 2.10 in your instance.
You will need to get ASDM if there is no asdm bin image on your ASA...
