Realistic Occlusion for depth effect

Hi, I am new to babylon JS. I am an intermediator in Threejs. In Threejs, we use aoMap for Ambient Occlusion to get realistic depth feel and aoMapIntensity to adjust the depth value. How to get that effect in babylonjs. I am using PBRMaterial .

If using the PBRMaterial in Babylon, you have the ambientTexture and ambientTextureStrength properties: Mastering PBR Materials | Babylon.js Documentation
