Spring Shell integration with IntelliJ console - intellij-idea

Question

I'm using Spring-Shell v2.1.4 with IntelliJ Utlimate IDE. If I use a Flow component in a shell method I find that it does not work when launched within IntelliJ but works fine from a plain Bash terminal.
For example if I have a simple #ShellMethod using the example code from the above link:
#ShellMethod("Testing for flow component")
public void flowTest() {
Map<String, String> single1SelectItems = new HashMap<>();
single1SelectItems.put("key1", "value1");
single1SelectItems.put("key2", "value2");
List<SelectItem> multi1SelectItems = Arrays.asList(SelectItem.of("key1", "value1"),
SelectItem.of("key2", "value2"), SelectItem.of("key3", "value3"));
ComponentFlow flow = componentFlowBuilder.clone().reset()
.terminal(this.terminal)
.withStringInput("field1")
.name("Field1")
.defaultValue("defaultField1Value")
.and()
.withStringInput("field2")
.name("Field2")
.and()
.withConfirmationInput("confirmation1")
.name("Confirmation1")
.and()
.withPathInput("path1")
.name("Path1")
.and()
.withSingleItemSelector("single1")
.name("Single1")
.selectItems(single1SelectItems)
.and()
.withMultiItemSelector("multi1")
.name("Multi1")
.selectItems(multi1SelectItems)
.and()
.build();
flow.run();
}
The method 'executes` but there is no interaction with the user:
Compare this to executing in genuine Bash terminal:
This older question is similar but it refers to an earlier version of Spring CLI and the recommended solution there is a VM argument for which the stated argument no longer appears to exist in the version of Spring Shell I am using.
Is there an updated version on the VM argument or an IntelliJ run-configuration setting to give better integration with the IDE?
