I find mine on the left panel just below the trash (image 1). If you don’t see that, doublecheck that you’re in the right account (mine is ZigZag and I could use the dropdown for it to select a different account where I might not be an admin). Also, is it possible someone downgraded you from an admin? If you are able to click on Admin, but not seeing what you expect, the tabs are now on the left panel (image 2).
