I have nine 240AC in a network that are all on POE connections to a Cisco switch which is fiber attached to a Cisco Firepower 1120. I need to add another 240AC where there is not an ethernet connection. I have a power injector. The question is how to I add the new 240AC wirelessly to the network? I have read that this is possible, but I cannot find a set of steps unless this is not possible.

u cant add a Cisco 240AC AP wirelessly as a mesh/repeater in this setup,this APs require a wired uplink (PoE or injector) to join WLC..
if u need wireless extension, u will need a mesh-capable model (e.g., Cisco Mesh APs) or run eth cable to new location

https://www.cisco.com/c/nl_nl/support/docs/smb/wireless/CB-Wireless-Mesh/1768-tzep-Cisco-Business-Introduces-Wireless-Mesh-Networking.html (unfortunately Dutch version)
both mention 240AC as mesh capable.
prerequisite: you need a minimum ios version!
With firmware version 10.4.1.0 or earlier, your CBW 140AC, 145AC, and 240AC APs could only be used as Primary Capable, Root APs. Starting with firmware update 10.6.1.0 and moving forward, there is a new option to configure an Access Point as a Mesh Extender.

you need to connect the "remote" AP temporarily to the wired network, so it can join your existing primary AP
what other steps are you missing in the document ?

your post seems garbled, I guess you tried to include some images, but they do not show.
dit you execute step 2 ?
Step 2
Log into the Web UI of your CBW Primary AP. Click on the light green arrows in the upper right-hand corner of the Web User Interface (UI) to enter Expert View.

the option you show in the word document needs to be set first, as described in prerequisite-2
