The belt broke in my dryer, I purchased a new one from appliance parts pros, when I took the front off the dryer to replace the belt the pulley bracket was laying in the bottom of the dryer. With the instructions I received with the belt I can’t tell how the belt goes on the pulley bracket or how the bracket needs to go back in the dryer.
This should help

The idler wheel assembly will fit into a couple slots in the machine’s base.
