Excluding from a Cypher query paths that go through a specific type of node - neo4j

Question

what I need is to refine this query:
MATCH
(u:User)<-[:CAN_SEE]-(c:Company)-[:CAN_SEE*]->(tc:UserView)
WHERE NOT (u:User)<-[:CAN_SEE]-(c:Company)-[:CAN_SEE*]->(:User)-[:CAN_SEE*]->(tc:UserView)
AND u.entityId=$userId and tc.entityId=$targetUserViewId
RETURN tc
I need to find UserView nodes directly visible from User u without passing through another User.
EDIT: I'M NOT searching "what users are directly pointing to a given view". I want to know what views can be reached from a user passing through his own attached company and potentially other nodes (not presented in the example graph). See sample data and the last phrase of the question for a reference of the intended result.
The query works fine if there is a single path to the UserView: if the path is direct, tc is returned; else, if the path goes through another user, no result is returned.
The problem arises if there are more paths from u to tc, some legal, and some not: I want that tc is returned, because at least a good path exists, but I get no result.
I understand that my query is wrong, because it says "search a tc that can't be accessed passing from another user", but what I really need is "search a tc that can be accessed in some manner without passing from another user"...
How can I fix my query?

Now execute:
MATCH
(u:User)<-[:CAN_SEE]-(c:Company)-[:CAN_SEE*]->(tc:UserView)
WHERE NOT (u:User)<-[:CAN_SEE]-(c:Company)-[:CAN_SEE*]->(:User)-[:CAN_SEE*]->(tc:UserView)
AND u.entityId='76f1bf95-6819-4aea-b1c3-4d138eb40cd3' and tc.entityId='fbd5cb12-0685-46e6-a672-2770f2140bf5'
RETURN tc
This returns nothing, I would like to have the view fbd5cb12-0685-46e6-a672-2770f2140bf5, id=9 because a path exists between the user and the view NOT passing through another User.

Answer 1

This seems to do the trick, I hope it's correct... but I think there should be a much better solution using another description of the path...
MATCH p=
(u:User)<-[:CAN_SEE]-(c:Company)-[:CAN_SEE*]->(tc:UserView)
WHERE u.entityId='76f1bf95-6819-4aea-b1c3-4d138eb40cd3' and tc.entityId='fbd5cb12-0685-46e6-a672-2770f2140bf5'
AND none(x IN NODES(p) WHERE ( 'User' IN LABELS(x) and x<>u ))
RETURN tc

Answer 2

... find UserView nodes directly visible from User u without passing
through another User
MATCH (tc:UserView)<-[:CAN_SEE]-(u:User)
WHERE u.entityId='76f1bf95-6819-4aea-b1c3-4d138eb40cd3'
RETURN tc
Or, if you want to limit it to a specific UserView:
MATCH (tc:UserView)<-[:CAN_SEE]-(u:User)
WHERE
u.entityId='76f1bf95-6819-4aea-b1c3-4d138eb40cd3' AND
tc.entityId='fbd5cb12-0685-46e6-a672-2770f2140bf5'
RETURN tc
