Clean all traces of MS Teams sign-in on laptop

I used my business  email  myname@company.com  once to have MS Teams meeting on my wife's laptop.  She has her own personal login to MS Teams which is  her_surname@hotmail.com .  She is participating now in online course and training company  provided a link to join  a meeting in MS Teams.  She clicked on this link  and it invoked MS Teams with my business credentials . She didn't pay attention to it  and joined the meeting as myself.  After that any attempt to join the meeting again  as herself  after click on the link in a browser  was unsuccessful.  The following steps didn't help :

1. Launching MS Teams  app and explicitly select her credentials. Click on the link invokes another instance of MS Teams with my credentials.

2. Disabling the device using my business account  in https://myaccount.microsoft.com/device-list

and rebooting laptop and selecting her credentials again on MS Teams start-up. Click on the link still opens another instance of  MS Teams with my credentials.

What I see in a browser :
laptop-name
Device is disabled   |  Organisation Status  Active

Basically what I want is to clear any traces about myself ideally in MS Teams only  or completely  on this device ( I am office365 user for my business email ).  I.e. when MS Teams is launched, I don't want to see myself in the list  of sign-ins.
