Increasing 2015 Macbook Pro's storage

[edavt04]

Hey there!
I have a Macbook Pro, early 2015, 500 GB, El Capitan Version 10.11.6.

I bought this Samsung memory card on amazon (Samsung EVO+ 256GB UHS-I microSDXC U3 Memory Card with Adapter (MB-MC256DA/AM) , and I wanna add it in the slot on the right hand side so increase my storage as I only have 50 GB left.
I worry a little but if it's the right memory card though as I am not tech-savvy at all.
Would this work? If not, can you please recommend what would work?
I live in the USA

It should work but I got this one instead: https://www.amazon.com/gp/product/B07H27BZYR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

$4 more and twice the storage. I'd get the 1 TB but the cost/GB is a lot higher.
