Switch on the Camera Control API (one time)
ComputerCanon developer siteCCAPI Activation ToolCanon ships CCAPI switched off on most cameras. You turn it on once per camera and it stays on.
Make a free account on Canon's developer community (developercommunity.usa.canon.com for the Americas, developers.canon-europe.com elsewhere). Download the CCAPI Activation Tool. Connect the camera to the computer by USB, turn it on, run the tool.
Afterwards a new Camera Control API item appears in the camera's wireless menu, next to Connect to smartphone.
Bodies reported to ship with CCAPI already on, no tool needed: EOS R1, R5 Mark II, R6 Mark III, R6 V, R50 V. That list comes from a third party, not Canon. The EOS 250D / SL3, R50, R8, R10, R7, R6 II, R5, R6, R3, RP, 90D, T8i and M-series bodies need the tool.
