How can Named Dispatch be tested without publishing to marketplace?

I am developing a capsule and want to test if it works as desired with Named Dispatch.

However, I am unable to trigger the default action in Simulator or as a private capsule on my device.
Instead of the default-action, another action (that does have Training entries) is invoked.

The problem seems to be, that before testing, the capsule has to be set. Therefore, named dispatch is circumvented.

How can Named Dispatch (as described here https://bixbydevelopers.com/dev/docs/reference/type/capsule-info.dispatch-name#how-named-dispatch-works) be tested without publishing to the marketplace?

Current configuration

• default-action (MyDefaultAction) is set appropriately in capsule.bxb.
• There are no Training entries for the default-action.
• I am using the commands from this list: https://bixbydevelopers.com/dev/docs/reference/ref-topics/meta-commands.de-de

You can use one of the seven reserve utterance to test in IDE simulator:

"speak to %dispatch-name%"

"talk to %dispatch-name%”

"start %dispatch-name%"

"load %dispatch-name%"

"ask %dispatch-name%"

"talk with %dispatch-name%”

"use %dispatch-name%"

Remember that it is only valid for en-US target. You can check out Github example and more details in this KB article.
