Rotate player camera in XR VR toward object not working

Unity Engine

HI All,
Been trying for a few days to make oculus headset to turn toward an object. Tried, lookat and toward, each with different syntax/override, also tried with eulerangles (difference of two points) nothing works.
I have a table, I want the cam to look at table when spawning. It spawn at right place and height, but it stays in the direction where I was looking at when I pushed start.
Last try, code is executed when player wear HMD:

Vector3 location = new Vector3(0.0f, 0.0f, 0.0f);
            location = Cam_desired_pos_rot.transform.position;//wanted position
            xrorigin.transform.position = location;//position xrorigin and cam, works OK
            //rotate origine-cam toward table
            location = mytable.transform.position;//get table location that we want to look at
            My_Camera.transform.LookAt(new Vector3(location.x, My_Camera.transform.position.y, location.z));

Camera is child of xrorigin\offset. Tried to rotate xrorigin also.
Must I turn off HMD controller ?
NOTE: I read correct position and rotation of both xrorigin-cam and table.
Pretty sure I miss something obvious here…
TIA for any help, reference or suggestion.
Regards,
Robert

First, note that jerking the player’s head around is going to be a pretty bad VR experience.

Generally you don’t move the camera in VR.

If you want to move and rotate the the player, you do so via the root (XR Origin in my setup), leaving the player to continue rotating their head however they like.

Otherwise yeah, pretty sure the HMD is gonna live-drive that orientation always.
