Looks like you are using latest version and referring to older learning material. CFD post does not support reading Mechanical 2021 or later result file, so it will not allow to make those connections.

Please try post-processing of FSI results in Ensight. Refer a following tutorial to know more about post-processing in Ensight. Postprocessing System Coupling's Co-Simulation Results (ansys.com).
