To add this option to your form, access the Editor and click on the Submit button area. From the left-side panel, tick the checkbox Reset under Options → Additional buttons.
Once you have enabled Reset button, a new section will appear in the left side panel, Reset button, from where you can edit the text shown on the button.
When you preview your form, you’ll see that the new button has been added next to the Submit button. Respondents simply need to click it in order to clear all the input they have provided and start from scratch.
