In my account settings I'm linked to my work Google Drive account.  However while building a chart I tried to replace/add data from Google Drive and accidentally selected my personal Google Drive account.   Now when ever I try to save or upload data from Sheets it tries to connect to my personal Google Drive account.   

I was able to fix this by logging into my personal Google Drive account and going under 'Google Account' settings.   From there I selected Security - Secure Account.  Under Security Checkup there is an option to manage Third-Party Accounts.  I found the Lucidchart access and selected 'Remove Access'.     From there I returned to my Lucidchart and tried to import data again from Google Drive sheets.  This time 'Google Sheets Permissions' window opened in Lucidchart asking me to authenticate the link.  I selected 'Authenticate' - - after which it allowed me to select the Google Drive account I wanted.  This time I got it right and selected my work account.
