Following are the required changes:

- Titles within the Pop-Ups needs to be in Bold
- The title should have accurate color which is the color of buttons.
- Font Family should be "Inter"
- The buttons should be in rectangle
- All the buttons should be of actual size.
- Please use **Actual Buttons** for GitHub and Google with proper icons on the SignUp page
