Implementing controlled phase shifted PWM on STM32F051R8T6 or STM32G030C8

I want to develop a full bridge converter, for which I need two PWM channels with complementary outputs. In order to turn off the load, I need to implement phase shift on one of the PWM channel and its pair(as shown in the image). I began by using STM32F0 discovery board (having STM32F051R8T6) and could generate complementary PWMs with dead time insertion. But later did I realize that I need to phase shift one PWM channel out of it. How do I go about implementing a controlled phase shift PWM in STM32F051R8T6? (can also use STM32G030C8 or STM32G071RBT6).

I thought I could post a new query with the output waveforms I could capture.
