Question rotate spawned particles to face origin of Set Position (Shape: Arc Circle)

Hey guys, Im wondering how I can rotate each individual particle so that they all face the origin of the circle they are emitting from. Ideally, they should all face a line from the origin of the cirlce pointing straight out of the paper (axis X in the screenshot below):


in this screenshot, Ive drawn the desired orientation of each point. For every point, their orientation should be the save as the tanget of the circle at that point.

I know Set Position (Shape: Arc Circle) stores in the direction attribute a vector between the spawned position and the origin of the circle, but Im struggling to find the math that will rotate the particle to face such a direction.

What Ive tried so far:
Ive treid the orient block in Output Particle Quad set to face a line with points (0, 0, 0) and (1, 0, 0), but the result is quite weird. So I dont think orient is the way to do this? Im looking for a specific rotation around the x axis for each particle so that they face the origin of the circle.

 

If this is wierd because they kind of rotate towards camera then you can use orient:advanced,
or the second way - calculate the initial rotation in Init context using LookAt, but you need safe check for collinear up with direction.
