4 wires protrude from the switch

Hello! Please tell me what’s what. Making repairs in a new house. I decided to remove two single-key switches (toilet, bath) and put one two-key in their place. With the switch, so that from the toilet, everything is clear (phase zero is nothing more). And from the switch from the bath, 4 wires stick out. Checked for phase - one. What are these 2 "extra" wires? And what to do with them? Thanks in advance for your responsiveness!)
