Add Sets to the Library
Add our design sets to the Oxygen library
Just copy the design set key you have got from the previous steps. And go to your Oxygen settings -> Library page to add our design kit to your Oxygen Builder.

As shown in the image above, you need to click the check box of Enable 3rd Party Design Sets option. And then click on Add Design Set to go to the next step.

Now paste the license key you have copied and click on Add Source Site button.

If you see our domain added under the 3rd Party Design Sets, that means our design set is added to your library successfully.
Now you can access our blocks in the Oxygen Builder in a regular Oxygen way, as you normally access any other design kit.
