What is the objective of this exercise?  Is it to prove the wireless clients able to "hit" 802.11ax speed or to connect only to 802.11ax protocol?

[sonic1111]

To connect wifi 6 802.11ax protocol

because hardware ap and client is capable to run wifi 6 protocol

thanks you for you reply

Not sure why the AP is detecting the wireless client to only support 802.11ac.  

I am not really familiar with eWLC but have a look at this guide (Configuring 11AX) and see this helps.

That could be one of two issues, or this is a cosmethic issue on the IOS-XE software (I've found that with certain codes COS-APs shows 2 spatial strrams clients connecting with 2 streams but using MCS Index for 1ss in the WLC CSCvx54426) or this is a defect on the M1 side as it happened on early stages with driver firmware and some 802.11 features on MacBooks.

update 

I tested with client samsung s20 it show 80.211ax protocol with c9120ax 17.6.1 EWLC

in my opinion there are two possible incompatibility of ipad m1 driver and cisco 9120 software
