No submit button when submitting captcha solution


New member
I know how to use the 2captcha API. After getting the solution I change the text area to display the inline or delete the section to get the white box. But the site I want to use this on does not have a submit button. And pressing ENTER does not submit the captcha response

example of site code:

<textarea id="g-recaptcha-response" name="g-recaptcha-response" class="g-recaptcha-response" style="width: 250px; height: 40px; border: 1px solid rgb(193, 193, 193); margin: 10px 25px; padding: 0px; resize: none; display: none;"></textarea>

Is there a way to submit the solution if there is no "submit" button?
