Consider going with 2 bay docking station. https://www.amazon.com/Sabrent-External-Duplicator-Function-EC-HD2B/dp/B0759567JT
Otherwise, get StarTech Dual HDD enclosure for the project. https://www.amazon.com/StarTech-com-External-Dual-Drive-Enclosure/dp/B07116PMPD
More than likely that adapter is under powered. It might work fine on a SSD but not on a hard drive. I would recommend returning it and getting something like this.
If it's just one or two drives, you can use something like this.

Then if you see yourself really using it, you can look into upgrading with a cleaner / enclosed DAS.
Nah you can just dock the SSD just like this
