Is it possible to show or hide a tab dynamically within the store configuration menu depending on a condition? I'm writing an extension using an OAuth 2 token, and want to hide tabs in the menu if there's no token. For example, say I want to hide the "Services" menu tab shown below. I know you can hide or show depending on visibility scope (showInWebsite, showInStore, etc.), but I want to show or hide dynamically.
Here's a portion of my MyCompany/MyModule/etc/adminhtml/system.xml:
<tab id="mycompany" translate="label" sortOrder="500">
<label>MyCompany Tab</label>
</tab>
<section id="mycompany_account" translate="label" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
<class>separator-top</class>
<label>Account</label>
<tab>mycompany</tab>
<resource>MyCompany_MyModule::settings_configuration</resource>
