Directly go to this link: S: Request A Quote to install the app.
After adding the app to the store is complete, you need to embed the app in the theme:
Go to Integrate Theme from the left sidebar -> Select the theme you want to apply -> Click the "Go to Theme Settings > App Embeds" -> Click the Save button in the upper right corner.
If you want to preview the application on an unpublished theme, then follow the same steps as above.
