Allow certain accounts to have permissions to invite guests to Teams

Hi,

I am trying to enable the 'Allow Guest' access to Teams. However, I have an issue. My boss wants certain users to have such access, bacically himself and the management (a total of approx. 12 people). 

I cannot find a way to allow guest access permissions to certain users only in my Office 365 A3 educational license.

I read the following article:

However, I cannot find any information on the net on how to restrict is to certain users once enabled. I only found out that the owner of the Teams chat will have access to invite guests. But I don't wont ANY owner to have such permissions.

Is there a way to grant the guest access to certain users only please?

Thanks in advance.
