In your course content area:
Original View: Go to Build Content > [LearnSci Tool].
Ultra View: Go to + > Create > Teaching Tools > LTI Item.
Select an activity using the content selector and add it to your course
In the settings for the activity, tick Open in New Window.
Save the item.
In the course content list:
Hover over the LTI item.
Right-click and choose Copy Link Address (or similar, depending on your browser).
This URL contains the secure LTI launch with the correct Blackboard parameters.
Edit the text block where you want the link.
Highlight the text (e.g. Launch activity here).
Click the Insert/Edit Link button in the editor toolbar.
Paste the copied URL and tick Open in New Window.
Save.
If you don’t want the standalone item to appear in your course content list, set it to Hidden from students.
The inline link will still work because it points to the same launch URL.
Students see only the inline link inside your content.
Clicking it opens the LTI tool in a new window/tab.
This avoids the missing ellipses issue and gives you control over window behavior.
