How to hide off certain areas of the account page?

Hi,

I'm trying to hide off the invoice section for on the account page. I was told to use the following code:

.ms-account-wrapper h2:nth-child(4), .ms-account-wrapper table:nth-child(5) {
display: none;
}

This worked for my admin access (full access) but it does not work for my other membership plans. Could you advise on how to resolve this please?

Support access has been granted as per the attached:

Many thanks,

Ash
