Hi @kartik-budhiraja, thank you for your interested in our project. As you can see it is an issue on or lowest prio because we need to make changes in the way we publish xlayers at this moment.

However, you can work on this issue and we will merge it when everything is set up for this feature.

If you have any questions let us know we will help you where we can.
