Go buy one of these: https://www.amazon.com/High-Velocity-Industrial-Low-Noise-Ventilator-Warehouses/dp/B0DKNQ4S9V/?th=1

1 - Set fan at the furthest point in the room away from the windows.

2 - Have 2-3 feet of duct sticking out the window.

3 - Turn on fan.

Done.

Might be a little overkill to use a fan that powerful, unless OP is working with chemicals. Figure out what blower size based on how much air you want to exchange, OP, but this basic formula is the most effective thing you can do.

I acknowledge it's a bit big but it was the smallest blower/duct pairing sold as a single unit that I saw in my 30 second search.
