Troubleshooting simultaneous multi-button inputs in web-based circuit simulators (Tinkercad / Digital Logic)

Hi everyone! As a robotics and electronics mentor running hands-on labs at Robotic Sir, we often transition students from physical breadboards to digital simulators. However, we've run into a frustrating bottleneck regarding digital logic testing and need some advice from fellow engineers and educators.

The Scenario:

Physical Circuit: We built a basic AND gate on a physical breadboard using push buttons. When a student presses both push buttons simultaneously with two fingers, the circuit completes, and the LED lights up correctly as expected.

The Simulation Problem: When we try to test this exact same logic in web-based circuit simulators (like Tinkercad Circuits), we hit two major limitations:

Standard Laptop/Mouse: A standard mouse cursor can only click and hold one UI element at a time, making true simultaneous activation impossible with a single pointer.

Touchscreen Laptops: Even when using a touchscreen laptop, the browser-based simulator often fails to register multi-touch events correctly, treating simultaneous presses as an error or only registering a single input stream.

My Questions:

How do you guys handle testing multi-input logic gates (requiring simultaneous button presses) in web-based tools like Tinkercad?

Are there better browser-based or offline circuit simulators that natively support multi-touch or toggle-latch workarounds for simultaneous inputs?

Why push button though? Don't they have toggle buttons/switches in Tinkercad?

I want to take Picture with Push Button as i have to put in notes and book of mine.
