New Role is not working

I created new role called “IT Employee” and I assigned this role to one of the users, but when i open this user, I couldn’t see anything as showed in the screenshot

Can you show the ss of
Modules allowed to the user of the role?

make sure minimum One DocType assign permission for this Role.

Thank you dear for your reply, but would you tell me how to assign permission for the role, please?

Thank you Sebin for your reply.
Only Buying module is allowed for the user as shown in the following screenshot

Give the permission of the modules to the used according to their needs and you can also create a shortcut of the modules.

You can add permission from here.
