Rule 706.6
Official source text from the 19 November 2021 Rules release
In a Planechase game, rolling the planar die will cause any ability that triggers whenever a player rolls one or more dice to trigger. However, any effect that refers to a numerical result of a die roll, including ones that compare the results of that roll to other rolls or to a given number, ignores the rolling of the planar die. See rule 901, “Planechase.”
