Dataset Read permission and build access

Thanks GilbertQ ,

I have another user who has been setup exactly as the first user i.e. only Read permission on the dataset. This user sees the below -

This is what we want for the first user too i.e. Read only access to the dataset without the ability to create reports. But, currently, the user sees this -

We checked the user's group membership. We have only limited set of users belonging to to two groups and the Admin/Contributor/Member of Workspace 1 who have build access to the Dataset 1. Everyone else has Read permission only. There are no apps built on reports using this dataset. I have deleted all links of reports (that I have access to). Most of the links that I had created had Read,Reshare permission. But, I get to see only links and apps from reports in workspaces that I have access to. Since there are two groups of users with build permissions, I am not sure if they have built reports on the dataset, stored it in a workspace that I cannot access and provided links to others with Build access. That is why I needed some API call or interface to check the reason for an user receiving "effective" build permission even though the user was only assigned Read permission by me.
