Login out of Data Service Like Facebook Ads- to Change Login for the same service to clients login

I tried logging out of the connector to Facebook Ads and Bing Ads.

I need to change the login credentials to the clients.

(I have a client with their own license of SuperMetrics)

I originally used a client Google Sheets Login- but my own login to Facebook Ads

So I need to change the FB Login to the client login (as they can see my other client data). It was just a short term fix- while I had the issue of my own login freezing when using Super Metrics

However - when I log out- the same login always return when the page refreshes automatically.
