SharinPix Plan can be added on any Lightning record page. The administrator just need to  drag and drop the component to the Record Layout and configure the component accordingly as follows:

SharinPix Plan Setting will be used to be able to determine the relationship between the object SharinPix Plan Item. The SharinPix Plan Item is the object which will save the annotations such as Marker, CircleMarker, Poloygon, Line, and Rectangle. 

Before you create the SharinPix Plan Setting, you need to create the relationship between your main object and the SharinPix Plan Item. Create a field of type lookup on the SharinPix Plan Item object. Save the field api name as it will be used for the configuration later. 

Steps to configure the SharinPix Plan Item:

1. Go to Salesforce Setup
2. Open Custom Metadata Types
3. Click on Manage Records for SharinPix Plan Setting Custom metadata type
4. Insert a label and name
5. Insert your object api name 
6. Insert the field api name of the field recently created on the SharinPix Plan Item

Once the plan setting has been configured. Create a Permission Set and give access to the SharinPix Plan Item object and fields. Note: Create and Edit access is needed in order for the feature to work as expected. 

Assign the permission set to the user who will be using this component.
