Problems with running the HRM example (ANT+)

Question

Hello. 
 I bought an nRF5340 DK board and am trying to run the HRM example (which uses the ANT+ protocol) on it. The standard (create a new application -> copy a sample) blinky starts and works well, while the standard HRM_TX does not work. I'm getting an error related to ANT+ initialization (hrm_tx: ant_plus_key_set failed: -63). I have an ANT+ key that I got from thisisant.com and I tried writing it into the prj.conf file and the ant_rpc.conf file (adding the line "CONFIG_ANT_LICENSE_KEY=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx -xxxx"). When it didn’t work out for me, I set “CONFIG_ANT_EVALUATION_KEY=y”. What is this error? How to fix it? 
 I installed everything strictly according to the instructions from the video: https://youtu.be/yg2p-scEyUA (except for the last step since I couldn't open Kconfig —> Menuconfig, see screenshot below)

Thanks in advance, Victor

As of sdk-nrf v2.6, ANT samples do not support sysbuild - the Kconfig auto header shows SB_* defines so I think that is the problem. The child image feature for the samples relies on partition manager to build ANT onto the network core. 
 I believe the sysbuild checkbox should be unchecked by default in VS Code, but please confirm.

FINALLY! I was able to defeat Ant+. Yes, thank you very much, the problem was in sysbuild. I saw in Nordic's YouTube video that they check the "sysbuild" box. I racked my brain for many days and couldn&rsquo;t figure out what the problem was. It's good that you were found! 
 
 Then I'll ask more questions. Please tell me where I can get acquainted with all Ant+ profiles (I'm interested in cycling ones). And in general, where is the documentation on working with Ant+ for beginners like me?
