How to submit token for recapcha from 2captcha, Python, Selenium?

I want to solve the ReCaptcha with the 2captcha API. Check this image, there is no submit button for the recaptcha.

I can send request to 2captcha and get the g-recaptcha-response from 2captcha. Then I use the following code to insert the g-recaptcha-response.

document.getElementById("g-recaptcha-response").innerHTML="TOKEN_FROM_2CAPTCHA";

But the problem is that there is no submit button to submit the recaptcha.

Can you please help me to find out the submit button to submit the recaptcha.

Thanks
