STM32F446RE ADC not triggered via TIM1 in injected mode

[KVeer.1]

Hello all,

I am trying to configure an ADC in injected mode via a trigger from TIMER 1. I want to trigger ADC whenever the timer RESETS. For this, I have set the TIM1's master mode to generate ADC trigger signal during timer RESET. I have configured ADC in injected mode to trigger for the same and have also set the ADC interrupt in trigger mode.

However, I found that it doesnot trigger for whatever reason. I have attached my ADC initialization code for you guys to take a look. Could you tell me where I'm going wrong?
