How to set pwm to ppi mode?

I want to use ppi to drive PWM. Attachment is my code files, it can't work.

How should I configure it.

bool pwm_play_ppi_task_event_init(pwm_play_t *pp)
{
#if defined(__ZEPHYR__)
    //Has IRQ_CONNECT or IRQ_DIRECT_CONNECT accidentally been invoked on the same irq multiple times?
    // IRQ_CONNECT(NRFX_IRQ_NUMBER_GET(NRF_GPIOTE_INST_GET(0)), IRQ_PRIO_LOWEST,
    //             NRFX_GPIOTE_INST_HANDLER_GET(0), 0, 0);
#endif    
    nrfx_err_t err; 
    if(NULL == pp)return false;

	 nrfx_gpiote_trigger_config_t trigger_config = {
		.trigger = pp->trigger,
		.p_in_channel = &pp->gpiote_channel,
	};

	 nrfx_gpiote_input_pin_config_t input_pin_config = {
		.p_trigger_config = &trigger_config,
        .p_pull_config = &pp->pin_pull,
        .p_handler_config = &pp->gpiote_handler,
	};

    err = nrfx_gpiote_init(&pp->gpiote, NRFX_GPIOTE_DEFAULT_CONFIG_IRQ_PRIORITY);
    if (err != NRFX_SUCCESS && err != NRFX_ERROR_ALREADY) {
        LOG_ERR("gpiote_init failed with: %x\n", err);
		return false;
	}

	err = nrfx_gpiote_channel_alloc(&pp->gpiote, &pp->gpiote_channel);
	if (err != NRFX_SUCCESS) {
        LOG_ERR("gpiote_channel_alloc failed with: %x\n", err);
		return false;
	}

	err = nrfx_gpiote_input_configure(&pp->gpiote, pp->pin, &input_pin_config);
    if (err != NRFX_SUCCESS) {
        LOG_ERR("gpiote_input_configure failed with: %x\n", err);
		return false;
	}
	nrfx_gpiote_trigger_enable(&pp->gpiote, pp->pin, true);

	err = nrfx_gppi_channel_alloc(&pp->gppi_channel);
	if (err != NRFX_SUCCESS) {
		LOG_ERR("gppi_channel_alloc failed with: %x\n", err);
		return false;
	}

	nrfx_gppi_channel_endpoints_setup(pp->gppi_channel,
    nrfx_gpiote_in_event_address_get(&pp->gpiote, pp->pin), pp->task_addres);
    LOG_INF("gppi_channel %u, gpiote_channel %u, task_addres %u", pp->gppi_channel, pp->gpiote_channel, pp->task_addres);
    return true;
}

These code can work.
