EXISTS with multiple pattern elements doesn't work as expected

[edc-lib]

Description

I've encountered what appears to be an issue with the Cypher.exists() method when using multiple pattern elements. When I try to create an EXISTS clause with multiple pattern elements using a List, the test fails with an unexpected Cypher output.

Environment

• Neo4j Cypher DSL version: [2024.5.0]
• Java version: [17]

Reproduction

I've created the following test case:

@Test
public void testMultiPatternElementExist() {
    final Node user = Cypher.node("user").named("T1");
    final Node dept = Cypher.node("dept").named("T2");
    final Node parentDept = Cypher.node("dept").named("T3");
    final Statement statement = Cypher.match(user)
            .where(Cypher.exists(List.of(user.relationshipTo(dept, "dept_id"), dept.relationshipTo(parentDept, "parent_id"))))
            .returning(user).build();
    Assertions.assertEquals("MATCH (T1:`user`) WHERE EXISTS { (T1)-[:`dept_id`]->(T2:`dept`),(T2)-[:`parent_id`]->(T3:`dept`) } RETURN T1", statement.getCypher());
}

This test fails. However, I can make it work by using the following alternative approach:

Cypher.match(user).where(Cypher.match(user.relationshipTo(dept, "dept_id"), dept.relationshipTo(parentDept, "parent_id")).asCondition())

Question

Is this a bug in the library, or is the Cypher.exists(List<PatternElement>) method intended for a different use case? If it's designed for a specific scenario, could you clarify the intended usage?

Thank you for your help!
