Component:

<aura:attribute name="record" type="Object" description="The record object" />
<aura:attribute name="recordError" type="String" description="An error message bound to force:recordData" />

recordId="{!v.recordId}"
fields="Subject, Description"
targetFields="{!v.record}"
targetError="{!v.recordError}"
recordUpdated="{!c.handleRecordUpdated}"
mode="VIEW"/>
Case Id: {!v.recordId}<br/>
Case Subject: {!v.record.Subject}
</lightning:card>
</aura:component>JavaScript:
({
handleRecordUpdated : function(component, event, helper) {
var eventParams = event.getParams();
if(eventParams.changeType === "LOADED") {
console.log( 'Record Loaded' );
var flow = component.find("flowData");

} else if(eventParams.changeType === "REMOVED") {

CORS does checks for the headers in the HTTP Requests and responses. If the domain1 wants to allow requests from domain2, it will set Access-Control-Allow-Origin Header in its responses to domain 2. So, the browser will allow the web page from domain2 to make requests to the domain1.
11. Muting Permissions in Salesforce Permission Set Group.
Muting lets you customize a permission set group by muting (disabling) selected permissions in it. To mute a permission, you add the permission to a muting permission set in the selected permission set group. When you mute a permission in a permission set group, the muting affects only users assigned to the permission set group, not users assigned directly to a permission set outside of the permission set group. So, muting offers you great flexibility when you design your permissions model.
