Which button pressed on Pointerup

This issue isn’t at all important (I can see that there is a lot of more important features and bugs) but I was just wondering about the pointerup issue (https://github.com/photonstorm/phaser/issues/4348). I have to sumbit a project soon and I was just wondering if something like “rightButtonReleased()” would be in the new Phaser 3.18 update or should I continue using the native event buttons value? I have to see what mouse button was pressed on a pointerup event.

Thank you,
