Submit on step

Hello. I have the 4 step form with calculated fields. On the 4th step shows the calculations result.

I need to send email (submit) on the 3rd step, however it doesn’t work even if I insert native cf7 submit tag. It’s just redirects to the next (4) step and doesn’t send email.

However if I insert [submit "Send"] to the 4th step and press it, the form sends ok.

Here is my 3rd step code:

<div class="container">
	<div class="row">
		<div class="col-md-6">
			<div class="contacts__title">Downloads & Revenue</div>

			<div class="contacts__subtitle">These are the key metrics buyers care about most</div>
		</div>
		
		<div class="col-md-6">
			<div class="forma">
				[number* number-1 class:form-control placeholder "Proceeds (last 30 days), $"]
				[number* number-2 class:form-control placeholder "Downloads (last 30 days), $"]
				[number* number-3 class:form-control placeholder "Marketing costs (last 30 days), $"]


<div class="cf7mls-btns"><button type="button" class="wpcf7-form-control wpcf7-submit cf7mls_next cf7mls_btn action-button valid" name="cf7mls_next" id="cf7mls-next-btn-cf7mls_step-3" aria-invalid="false">Calculate now<img src="/wp-content/plugins/cf7-multi-step/assets/frontend/img/loader.svg" alt="" data-lazy-src="/wp-content/plugins/cf7-multi-step/assets/frontend/img/loader.svg" style="display: none;"></button></div>


			</div>
		</div>
	</div>
</div>

As you can see, I tried to use wpcf7-form-control wpcf7-submit classes to give the submit functionality to the button tag.

How to send the email on the step 3 pressing calculate or autosubmit on the step 4 without press the submit button?
