Ever since I heard that this feature was included in 4.5 I was eager to give it a spin, but since it is still in TP It was difficult to find any particular documentation regarding the feature, the only mention was in the release notes and some blog posts I found. Now since it was TP I was guessing that the feature would not appear in PRISM so I had to dig into the CLI.
I noticed that there was an command for FLR under the virtualmachine list-flr-snapshots, when I ran the command
ncli> virtualmachine list-flr-snapshots vm-id=00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633
Error: Nutanix Guest Tools are not enabled for this VM.
So again, where can I find the Guest Tools to do this ? in the CLI 
ncli> nutanix-guest-tools enable vm-id=00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633
VM Id : 00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633
Nutanix Guest Tools En… : true
File Level Restore : false
I saw that the file level restore option was disabled so I needed to enable it for a particular machine, which was in a protection domain.
ncli> nutanix-guest-tools enable-applications vm-id=00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633 application-names=”File Level Restore”
VM Id : 00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633
Nutanix Guest Tools En… : true
File Level Restore : true
Then I needed to mount the guest tools to the VM
ncli> nutanix-guest-tools mount vm-id=00051d07-74fe-2635-0000-00000000698a::5035e717-b404-916d-72d4-a8750120c633 Successfully mounted Nutanix Guest Tools.
This in essence will mount an ISO under the CD/DVD rom. My first mistake
After installing Java I could continue on with the configuraition. Now in the Nutanix Guest Tools CLI mode I can now look and mount my snapshots.
Using the commands
flr ls-snaps (to list out snapshots
flr attach-disk disk-label=labelname snapshot-id=idname
Then I can do a regular file explorer to my orginal content as it was during the time of the snapshot.
