Touch input pixel streaming unreal 4.27.2

I working on this Arch Viz project, the game has some touch input options, when I test using a computer and mouse, everything works, but when testing with pixel streaming for android phone only the button respond to touch but not the custom blueprints geometry.
I have tried adding the blueprint touch by the option click but still the blueprint object doesn’t respond.
