Where are timer outputs connected?

For instance STM32H750VBT6 has many timers, but CubeMx does not show where their outputs would go. I don't want to mess (enable all of them) an existing design just to see where timer output are.

Hi guysSo I am developing a small PWM generator around the F334R8, it's overall extremely simple. All the work is done with another MCU sending data on SPI.On the F334R8, an EXT interrupt is called when the CS line is pulled down. From there the F3 l...
