how did they prevent the Nazis figuring out that the enigma code has been broken?

How did they get over the catch-22 that if they used the information that Nazis could guess it came from breaking the code but if they didn’t use the information there was no point in having it.

EDIT. I tagged this as mathematics because the movie suggests the use of mathematics, but does not explain how you use mathematics to do it (it’s a movie!). I am wondering for example if they made a slight tweak to random search patterns so that they still looked random but “coincidentally” found what we already knew was there. It would be extremely hard to detect the difference between a genuinely random pattern and then almost genuinely random pattern.

The British using misinformation to conceal crucial military secretes is nothing new in fact it’s partly where the “carrots are good for your night vision” idea comes from— the Brit’s claimed that they were feeding their pilots extra carrots because it improved their vision and made them better able to “find” German bombers during the blitz, when in reality they had developed an advanced radar system…. And in another case had been intercepting German naval transmissions and intercepting the ships and lied and said they had developed a sensor system that could detect [something] (I can’t remember the details) and the Germans believed the lie so they “solved” the problem by developing a radar absorbing paint to prevent detection by the sensor system (that didn’t actually exist)…
