To remove the test mode button (also known as the "Purple Hand" button) from your website in Webflow, you'll need to follow these steps:
1. Go to your Webflow project's dashboard and select the project you want to edit.
2. In the Designer, you'll see a "Settings" tab on the left-hand side menu. Click on it to open the project settings.
3. Within the project settings, navigate to the "Hosting" tab.
4. Under the Hosting tab, you'll see an option called "Form Notifications & Actions". Click on it.
5. Scroll down until you find the "Payment Section" within the "Form Actions" settings.
6. In the Payment Section, you'll see a checkbox labeled "Enable Test Mode". Uncheck this option.
7. Make sure to save your changes by clicking on the "Save Changes" button located at the top-right corner of the page.
By following these steps, the purple test mode button will be removed from your website, indicating that payments are no longer in test mode. However, please note that this button only appears in Preview and/or Published versions of your site. While in the Designer mode, this button won't be displayed.
