Hi christian.victoria
If your expectation is to show each icon as per each tenanted login user like the below, I suppose it is difficult for you to meet the expectation.
When employee of the company A logins web interface, the logo of the company A will show at the upper left instead of CA logo.
When employee of the company B logins web interface, the logo of the company B will show at the upper left instead of CA logo.
If the TEC502605 Junaid said did not help for you, I recommend you to raise the idea to meet the expectation in the future version.
Best regards, Kosei
