Hello @hemnathmouli @Ferdinand1945 @hirenshah @ghmercado @jkester1986 and everyone... Please how do i disable the button that is automatically added to the new custom account tab?

Is there a way to return the user to their account page after saving details from a custom tab? It currently gives a 404 when it tries to return to the custom tab.

How do I integrate zoom online meeting platform with UM plugin?
Thanks in advance.

Could we add a submenu within the custom tab? A sub-custom tab that is.
