OutlinePass in 8thWall

I have tried adding outline post processing effect in 8th wall using custom threejs pipeline. Yet I am unable to see the outline effect. I am using an onLongPress to call a function that adds selectedobjects(model) to outlinePass. Does anyone have any workarounds?

I have used web/customThreejsPipelineModule.js at master · 8thwall/web · GitHub for adding the custom pipeline and introduced the outline pass and effect composer in the same.
