Install MarkupGoogleRecaptcha on FormBuilder form

[couturef]

Hello,

My knowledge of ProcessWire is limited.

I would like to install Google reCaptcha V2 on a form that was previously made using FormBuilder. I have already installed and activated the MarkupGoogleRecaptcha module and entered the Google API keys. When I try to add a reCaptcha field to the form, it does not show up.

Do I need to create the field myself? If yes, which field type should I use and how should I proceed?

Thank you,
