What is the safest foot stance and foot angle on heavy glute bridges and hip thrusts?

Hi, I am new for glute bridges and hip thrusts. I am doing glute bridges and hip thrust with a random comfortable stance but I want to make sure I am safely executing the glute bridges with right foot stance and foot angle.

For example, I am executing squats with 30-degree foot angle with a shoulder width stance. Deadlifts with 15-degree foot angle with a hip width stance. What is the formula for hip thrusts and glute bridges?

Note: I know this depends on the person’s build. Just consider an average person with average torso/leg length rate.
