Check https://www.ciscolive.com/c/dam/r/ciscolive/global-event/docs/2022/pdf/BRKEWN-2308.pdf Page 16. AP does connect to the edge nodes via VXLAN, while it talks to the WLC that handles the control plane.

B Fabric WLC Both fabric WLCs and non-fabric WLCs provide AP image and configuration management, client session management, and mobility services. Fabric WLCs provide additional services for fabric integration such as registering MAC addresses of wireless clients into the host tracking database of the fabric control plane nodes during wireless client join events and supplying fabric edge node RLOC-association updates to the HTDB during client roam events. https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html
