Basic nRF timer usage

Question

So what I understand from the lesson over here is that we have couple of timers available to us and each timer comprise of multiple compare/capture register which can be used to generate and service an interrupt when the value of CC register is equal to the set value. In the following code I am trying to implement this feature to toggle two different LEDs using two CC register. I have set the value in CC by converting ms to ticks. Essentially telling timer to service interrupts when values in CC register equals x milliseconds hence toggeling LEDs at different time intervals in correspondence to CC registers values . I am not sure what I am doing wrong. Would love to know if there is some concept I need to understand.

#include <stdbool.h>
#include <stdint.h>
#include "nrf.h"
#include "nrf_drv_timer.h"
#include "bsp.h"
#include "app_error.h"

#define LED1 17
#define LED2 18

const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(0);

void timer0_handler(nrf_timer_event_t event_type, void *p_context)
{
  switch(event_type)
  {
    case NRF_TIMER_EVENT_COMPARE0:
    nrf_gpio_pin_toggle(LED1);     
    break;
    
    case NRF_TIMER_EVENT_COMPARE1:
    nrf_gpio_pin_toggle(LED2);    
    break;
    
    default:
      //nothing
    break;
  }
}


void timer_init(void)
{
  uint32_t err_code = NRF_SUCCESS;
  
  uint32_t time_ms = 100;
  uint32_t time_ms2 = 500;
  
  uint32_t time_ticks;
  uint32_t time_ticks2;
  
  nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG; // Default timer config
  
  err_code = nrf_drv_timer_init(&TIMER_LED, &timer_cfg, timer0_handler); // init the timer with custom timer instance, config and handler for it
  APP_ERROR_CHECK(err_code);
  
  time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER_LED, time_ms); // convert ms to ticks so that timer compare register can generate interprit
  time_ticks2 = nrf_drv_timer_ms_to_ticks(&TIMER_LED, time_ms2); // convert ms to ticks so that timer compare register can generate interprit
  
  nrf_drv_timer_extended_compare(&TIMER_LED, NRF_TIMER_CC_CHANNEL0, time_ticks, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, true);
  nrf_drv_timer_extended_compare(&TIMER_LED, NRF_TIMER_CC_CHANNEL1, time_ticks2, NRF_TIMER_SHORT_COMPARE1_CLEAR_MASK, true);
}

int main(void)
{
    nrf_gpio_cfg_output(LED1);
    nrf_gpio_cfg_output(LED2);
    
    nrf_gpio_pin_set(LED1);
    nrf_gpio_pin_set(LED2);
    
    timer_init();
    
    nrf_drv_timer_enable(&TIMER_LED);
    

    while (1)
    {
        __WFI();
    }
}
