Note: This step may vary slightly depending on your account’s interface update:
Option A (older version): In the left-hand column, click Pixels.
Option B (newer version – more likely): In the left-hand column, click Datasets. Meta is gradually migrating all Pixels here.
In the middle column, check the box for the relevant Pixel (or Dataset).
In the right-hand column, enable the desired permissions:
