Is there any way to retrieve the URLs or a least the Names/IDs of all child lists that have lookup columns referencing the parent list in SharePoint. It is easy to find the parent list of a child list by expanding the lookup column with REST but I can't figure out a way to get the child lists of a parent. It seems like this should be possible since SharePoint has an OOTB WebPart to display related lists.
I know it can be done out of the box, but I need a way to retrieve the child lists with client-side code. This is part of a custom solution and I can't use out of the box web parts.
