Change AutoDesk Account used to open DWG file from SharePoint

[NCE-IT]

When I was testing the Open in AutoCAD Web App feature of Microsoft SharePoint Online, I used an old AutoDesk account to sign in AutoCAD Web. From then on when I open DWG file in SharePoint, an AutoCAD Web tab will be opened to open the DWG file, without asking me to sign-in AutoDesk again. It is like a linking between my Microsoft account and AutoDesk account has been established. 

Now I want to use a new AutoDesk account for this. How can I tell SharePoint (or AutoDesk) to use a different AutoDesk account to open AutoCAD Web?

Nothing in AutoCADWEB does that, sorry.
