If you'd like to remove a member from your dashboard, you can do so directly from the Company Members page.
You can do so by following these steps:
Click on your Account icon in the top right.
Select Account Management.
Select Company Members.
Find the user you'd like to remove, click on the three dots next to their name, and select the trash icon.
Please note that you must have equal or greater privileges than the member you'd like to remove.
