Dell Precision 5530 - need to add a SATA SSD to laptpop

Hi, please help me here. On my Dell Precision 5530 <Private data removed from public view. DELL-Admin>, i would like to add a SATA 2.5" SSD. I have removed the battery pack which takes up the entire bottom portion (one end to another). I dont see the drive cage or anything including a connector that's required for SATA HDD. How can this be done. please advise and let me know if any writeups or videos are available for the same.

thanks,
