How to define a right clic contextual menu list in dude?

Hello,
How to define the contextual menu list for each user when doing a right click on one device on Dude?
Indeed, even for guest users, it was in the contextual menu, “tool” and all the tools necessary to access to the device (such winbox).
I created a guest user, which should have the "read " permission and no (any) tool or few tools defined by myself.
How can i create it?

Thanks in advance.

I would have to say that it is a security flaw. You could give them web access instead…

Thanks.
