Forwarding DICOM study from dcm4chee to another modality

[Sorcerer Stone]

Hello All,
I am running dcm4chee-arc-light using docker image from Github.
To understand how dcm4chee works, I was able to send studies from an external modality to dcm4chee.
Now, I want to send a study inside dcm4chee to the external modality. I have been looking for a long time at the UI. But I am not able to figure out how this can be done.

Would someone kindly suggest how I can achieve this?

Is there some documentation on how dcm4chee-arc-light works? I came across URL that describes dcm4chee V2 (probably obsolete) and the UI describes in that web has no resemblance to the UI in dcm4chee-arc-light.

I have attached a screenshot of the AETitles in my dcm4chee setup (with the intended external AET where I want to send the study to highlighted) and another screenshot of the study in dcm4chee I want to forward.
Thanks in advance.
