Hi @dinakarks - You can upload the .pdf file in your course as ‘Slides Converter’ not as ‘File’ or add the file in your Channels.

channels are a good way to go and the asset can be configured to not allow downloading.

I’ve also shared via an embedded google drive link. You have to have https://drive.google.com listed under iFrame Allow List. 

Superadmin Menu > Advanced Settings > E-Learning > iFrame Allow List > add
