wp role accessing the settings

Hi,
thanks for the plugin. It really does what I expect from a sitemap. I appreciate ??

I would have a question related to user roles. I apologize if this question was already asked, i was not able to find in the different (few pages) I searched.
On my wordpress installation I created a special role, which is almost Administrator – called here after small-admin. For this small-admin role, I do not provide access to some rare sensitive data.
Accessing admin part with this “small-admin” role I do not have access to the plugin parameters. Seems only standard Administrators can have access to the plugin settings.
Is there a “custom” role for which i need to grant access to the small-admin in such way they can access the configuration? would it be possible to add such feature in the plugin, if this doesn’t exist? or a toggle in the settings restricting the role up to a given level?

thanks a lot
with my best regards,
B
