Recaptcha button in different languages

Hi everyone,
On the website I design I have a recaptcha button that I used from webflow resources. However this button is only in English. And I would like to have both English and German. So I designed my
own button that looks like recaptcha, but with this design the form does not work. The user ends up in a loop like on the video below. For now I came back to recaptcha provided by webflow, but maybe you can help me solve the issue how to make my own rectangle works properly.
