Implement getting/setting of "Advanced Permissions" (ACL) via OCS API

We use the groupfolder plugin.

As it looks for me, there is no no way to access the Advanced Permissions (ACL) feature for folder by remotecontrol.
I would expect it in OCS API. But i cannot find it.

Can you implement it?

This is my use case:
I program in a small team a software to generate template structures in nextcloud for similar workgroups on different locations. They have all the same workflow.
E.g. if a new work group starts, they shall have a predefined folder structure. Some people are admins, some have only read only status. ACL seems the right tool for us to allow to share files within groups as well as other groups. A manually configured setup works fine for us.
We made a webfrontent, to allow the management to create this structure by a simple button.

In Backgroup, Users are created and synchronized by LDAP feature. With OCS REST API it works great to make folders automatically. But we could not find a way to set the ACL rights for subfolders in groupfolders automatically.

To impement it, we use KOTLIN as programming language. Our project is opensouce. It is named feather and feather frontend and is published in gitlab.
