HP Pavilion X360 Sata 2.5" HDD Installation Issue

[Rakibkhan]

I want to install a 2.5" sata hdd in my HP Pavilion x360 - 14t Touch Laptop which Product number is 7XJ60AV. But when i open laptop's back cover, i've noticed that this laptop doesn't come with native hdd encloser as well as Hard Drive HDD Cable. Moreover, i'm unable to remove hdd slot's plastic cover, so that i couldn't install sata hdd. Someone please assist me to install hdd at ease. I've been attached some pictures with this post for better understanding.

Thank You.

Hey, I didn't find any solution here. My hp pavilion x360 laptop haven't come with sata hdd cable (Part Number:L51095-001) as well as it didn't come with native hdd rubber caddy/cover which part number: L51121-001. Moreover, the hdd space fill with fake plastic cover (shown in the picture) as my laptop was pre-installed with intel optane+250gb ssd. If somehow i buy the hdd cable and hdd rubber cover from local market, i can easily install 2.5" sata hdd/ssd in the hdd space. But i can't remove/ disassemble  the fake plastic cover which is already filled in hdd space. So my question is how to remove it without damage the laptop parts. 
Hope you understand my problem and resolve my problem.
