Rule 701.47d
Official source text from the 2 February 2024 Rules release
If multiple permanents are instructed to connive at the same time, the first player in APNAP order who controls one or more of those permanents chooses one of them and it connives. Then if any permanents remain on the battlefield which have been instructed to connive and have not done so, this process is repeated.
