Our script-based code is designed to be embedded in standard webpages. If you would like to embed it in Sharepoint, you can try embedding the extension URL inside an HTML iFrame tag. You can use some website that allows you to generate a standard iframe code like this one: https://iframe-generator.com
Steps
1. Go to the extension page and copy its URL.
2. Paste it in the URL field then copy the embedding code.
3. Use the iFrame script in Sharepoint.
