Matter physics overlap method

I noticed in the documentation for Matter Physics there is an overlap function.
https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Matter.MatterPhysics.html#overlap__anchor

however when I try:
this.matter.overlap(shot, this.shieldBack)

I get this.matter.overlap is not a function. (within my scene object)

Make sure you are running phaser 3.22 or later. It sounds as though you might run an older version.

Tried 3.21, 3.22 and 3.23

also Phaser.Physics.Matter.MatterPhysics.overlap()
Still no luck

There is definitely this.matter.overlap() in Phaser v3.23.0.

Ok, I tried 3.23 again and it’s working.
I thought I flushed my browser cache, but I guess maybe it held on to 3.21.
