Project: ShareLaTeX Integration

I am interested in the ShareLaTeX integration project for GSoC’19 and would like to know more details about the project. I have gone through https://github.com/JabRef/jabref/pull/2866. I would like to know what else is required in order to achieve the integration.
Also considering that ShareLaTex has now migrated to OverLeaf, wouldn’t it be better to allow Overleaf Integration? Or is there a problem with that approach?
