ᐅ Wastewater planning: placing the toilet next to or under the shower?

Good morning,

Today we received the slab foundation plans including the wastewater plans.

Now I wonder if it is acceptable for the wastewater from the toilet to run underneath the drain of the shower.

Sketch of pipe routing:
Main wastewater pipe ← Shower (Bathroom 1) ← Toilet (Bathroom 2) ← Shower (Bathroom 2)

The description is a bit vague. Could you share the plan? Based solely on the description, there is no objection as long as the slope is correct.

I have looked into it further, and odor traps will be installed. That answers my question.
