Note: When adding the component to the lightning page,
For the record page, only those configs will be visible where you have selected page type as "Record Page" while creating configuration.
For non-record page, only those configs will be visible where you have selected page type as "Non-Record Page" while creating configuration.
To add PWR Components to lightning pages, please follow the below steps:
From any Lightning record/home page, click on the Setup icon
Click on Edit Page
From the left panel, select the required component and drag and drop it on the page
Select a config name from the available list
Save the configuration and click the back arrow to navigate back to the page
Now you will be able to see the added component on the Lightning page
