Hi @el2030,

Thanks for the post!

It looks like the PDF is being displayed as a visual embed on the page, which means the extension can’t actually access or read the content inside it.

There are a couple of options:

- If possible, try switching the content to regular text instead of a PDF
- Or download the PDF and create a simple agent where you can upload the file and chat about it

Hi @el2030,

Looks like this might be the same situation as your earlier post. The content is likely inside an iframe or another kind of embedded container, which means the Chrome Extension can’t access it.

As a workaround, you can create an Agent with a User Input set to Long Text. That way, you can copy and paste the content and chat with the AI from there.

Thanks very much. based on my check,

It looks like the MindStudio Chrome extension can’t extract or access the page content from Brightspace’s `d2l/le/enhancedSequenceViewer` because the actual learning content is dynamically loaded inside a **custom web component** (`<d2l-sequence-viewer>`) via **shadow DOM** or JavaScript fetch calls.

- The **HTML source** I am seeing doesn’t contain the actual learning content.
- Brightspace loads content **dynamically via APIs** , so the raw HTML (`rawHtml`, `pageContent`, etc.) your extension receives is just a shell.

* * *

Would like to check if it’s possible to

Update the MSr Chrome extension logic to:

- Wait for the full page render (e.g., `setTimeout` or `MutationObserver`).
- Traverse the **shadow DOM** if needed (e.g., `.shadowRoot.querySelector(...)`) from `<d2l-sequence-viewer>`.

Tk u,
