Maven not finding dependencies in IntelliJ

I'm new to Maven and not quite sure what it's for but I thought it was for importing external libraries so that they are available while coding. I have imported the dependency and there's no error on it as can be seen here:

But when typing the import it all just comes up in red as if it's not found. It's not finding anything.

And if I paste the whole import line in it gets deleted automatically.

Is this not what Maven is supposed to do or is there something else to do before it will work? I also have it set to import Maven projects automatically.

EDIT: Just for clarity, of course it's in my pom.xml file otherwise it wouldn't be showing up in the external libraries in the screenshot above:

<dependencies>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>11</version>
    </dependency>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-graphics</artifactId>
        <version>11</version>
    </dependency>
    <dependency>
        <groupId>uk.co.caprica</groupId>
        <artifactId>vlcj</artifactId>
        <version>4.5.0</version>
    </dependency>
    <dependency>
        <groupId>uk.co.caprica</groupId>
        <artifactId>vlcj-javafx</artifactId>
        <version>1.0.2</version>
    </dependency>
</dependencies>

Additional EDIT: Some screenshots to show that typing the classes directly does not work any better. Intellij is just not finding anything:

javafx maven dependencies maven-plugin java

It seems this particular dependency is modularised per the Java Platform Module System. So, we need requires in the module-info.java file.

module com.sample {
    requires javafx.controls;
    exports com.sample;
    requires transitive javafx.graphics;
    requires uk.co.caprica.vlcj;
    requires uk.co.caprica.vlcj.javafx;
}

After this the dependency is suddenly visible and fully usable within the code.
