Using localstack on remote server (raspberry pi 4) still requires local image to be created/run

[therebelrobot]

Hi! Wasn't sure where to ask this question, but I've got localstack running on my rpi4 in my local home network, and while I can sort of connect to it by manually editing the connection URLs, tasks like creating an s3 bucket fails with an empty error popup, and it still requires a commandeer-localstack container be created/started on my local host, which isn't ideal, as i'm not using it locally at all. When I remove the container on my local host system it removes any ability to edit the urls further. Any ideas on how to effectively use a remote version of localstack with Commandeer?
