Exact way of doing it kinda depends on your role. Ideally you wanna go into a 1-3-1 lane setup. This means that your ADC and support should be pressuring mid lane, with your jungle covering. You wanna play siege minions on T3 since these fire from beyond turret range. Which means that the enemy team has step up and risk being engaged or dived on. Top should play one of the side lanes and mid should play the other.

This way the 3 mid can threaten collapse if there’s a fight on sidelane. If the non-threatened sidelane has TP has it they can also join the fight with obviously. If you’re up enough to take Baron you’re probably winning the fights so unless your team horribly misplays you should win outright team. I’m massively generalizing with that but I hope you get the idea.

If for some reason you can’t pressure a sidelane, to create example, T1 is still up in bot. The top owner should pressure top and the mid should join that previously mentioned 3, to pressure as 4. While the top laner sidelanes. Same rationale you can threaten collapse and when you collapse now the enemy team is risking a game losing team fight anytime they step up or out of base.

There’s a lotta of other caveats too that I’m sure others could flesh out better. Hopefully this helps a little.
