I have a data structure like this:

const rowData = [
    { path: "Erica", jobTitle: "CEO", employmentType: "Permanent" },
    { path: "Erica/Malcolm", jobTitle: "VP", employmentType: "Permanent" }
    ...
]

with the Client Side Tree Data we can easily use getDataPath to make this work. With the SSRM I have to use getServerSideGroupKey and isServerSideGroup instead of getDataPath. How can I use the SSRM with this data structure? Which values do I have to return in my two functions? I have to add that I cannot change my data structure.
