The error message also tells

The document tree is shown below.
The+resource+principal+named+Dynamics+365+for+Finance+%+Operations+was+not+found+in+the+tenant+named+XXXXYYYYY.+This+can+happen+if+the+application+has+not+been+installed+by+the+administrator+of+the+tenant+or+consented+to+by+any+user+in+the+tenant.
You+might+have+sent+your+authentication+request+to+the+wrong+tenant.
