Redirect users to accessible version of link if they do not have access to internal link

Users submit requests via an externally facing portal. Once that request is received, the team handling the request have one view of the request, while those who do not have that internal access can only see the publicly visible version of the request. My idea is that, when presented with a link to the internally visible request, if the user does not have access to view that request, that link would automatically re-direct to the externally facing version that is visible/accessible to them.
