Tinkerpop-3 Gremlin Not Found For Groovy-Project In IntelliJ IDEA

Question

Why can IntelliJ IDEA not resolve Gremlin for its SimpleExample?
I need to make a program that doesn't require intervention / manual steps, so I can't use the gremlin/groovy-shell at time of graph-database demonstration. How can you make a simple Gremlin-Groovy project?

Cannot resolve symbol 'Gremlin'

Reproduction

Steps

1. Select-Click a new project in IntelliJ IDEA
2. Fill-in fields and confirm for Gremlin-Project
   1. Language: Groovy
   2. Build System: IntelliJ
   3. JDK: corretto-11
   4. Groovy SDK: 4.0.2 enter image description here
3. Navigate-open Project Structure (IntelliJ IDEA)
4. Add libraries to Project Settings > Libraries or Platform Settings > Global Libraries
   1. compile group: 'org.apache.tinkerpop', name: 'gremlin-core', version: '3.6.3'
   2. compile group: 'org.apache.tinkerpop', name: 'gremlin-driver', version: '3.6.3'
   3. If I don't import these directly, then it will suggest older TinkerPop-2 which we don't plan to evaluate
      1. import com.tinkerpop.blueprints.Graph
      2. import com.tinkerpop.gremlin.groovy.Gremlin
5. Copy-paste latest found Groovy Classes with Gremlin found
   1. I couldn't find anything newer
6. Results:
   1. Expected: Import for Gremlin would be found: automatically or recommending
   2. Actually: No Gremlin found for IntelliJ IDEA to import for Groovy
      Cannot resolve symbol 'Gremlin'
