How Do I Use Dropbox on Windows 11 with a local User account?

When I set up my Windows 11 computer, it created an Administrator Account (called "Owner").  I put the Dropbox folder directly under the C drive instead of under C:/Users/Owner so that it would be accessible to all users on the computer.  I just created a local standard account (called "MyUser") that I sign into separately.  When I opened the Dropbox app on my standard account, it asked me to sign in.  It created another Dropbox folder under C:\Users\MyUser, which will put two redundant folders on my computer.  When I try to move the Dropbox folder location under Preferences/Sync, Windows asks me to sign into the folder but then Dropbox says that it cannot create a folder at that location.  So - two questions: (1) how do I use my existing Dropbox installation on this computer without creating a redundant folder, and (2) how do I undo what Dropbox just set up on my account?  Do I need quit Dropbox and delete the entire Windows user account? 

I suspect the answer is to NOT open the Dropbox app on my standard account, but instead to open the folder that was already created on the administrator account, and to edit and save in that folder.  If that's the case, I just need to know how to undo or uninstall the app/folder that was created on my standard account (I suspect I just have to delete my Windows user account and start over, but it would be nice to have an easier solution).
