Can't open embedded docs from a OneNote notebook in Teams

A colleague has a OneNote document in a Teams channel, with many embedded documents. If I open her OneNote within Teams, I can't open any of the embedded documents. The message says ""we can't open this file from OneNote. Would you like to download a copy?" However, if I open the notebook in the OneNote app, the embedded docs open correctly. Is this expected behaviour? Many of the Team members work in sensitive workplaces with tight security restrictions which prevent them from downloading files. We need them to. be able to open the embedded documents within the Teams environment. Also, is it relevant that my colleague originally created the OneNote in her OneDrive, then uploaded it to Teams, along with all the embedded docs - would that make a difference?
