Superdock : how to fix properly the SSD inside the Superdock

I posted this request on discord too....

I have a superstation one AND a superdock. I bought the SSD, format exfat ,etc.
No problem there.
Now... Now I can't fix the SSD properly on the bay, in side the Superdock , due to the "plastic lock".
By the way, be careful with this The "plastic thing" : I had to research 2 times, because it felt inside the super dock! Each time you have to fully open the superdock !!! Oh Boy....
On a normal PC, you use screws.
Here.. here I don't know . If someone has any "technic" or any tip with a correct brand of "plastic thing" compatible with the super dock, I'm all ears !! It's really a pain in the a** to fix the SSD inside the superdock !! Yeah I'm pretty mad, right now... 🤔
