How to Automate and Create P2 Container Link

For Flows, an Invocable class needs to be created which needs to be invoked from the Flow.

Under the Invocable class, one need to create a wrapper by setting the following attributes as per requirement:-

public class P2ContainerRequestWrapper {
 
    @AuraEnabled public String sApiKeyName {get;set;}
    @AuraEnabled public String sParentRecordId {get;set;}
    @AuraEnabled public String sTemplateName {get;set;}
    @AuraEnabled public String smsBody {get;set;} 
    @AuraEnabled public String emailSubject {get;set;} 
    @AuraEnabled public String emailBody {get;set;} 
    @AuraEnabled public String defaultMessage {get;set;}
    @AuraEnabled public datetime lastOnline {get;set;}
    //Add another Object to Allow Multiple Recipient
    @AuraEnabled public List<Recipient> recipients {get;set;}
    public class Recipient{
        @AuraEnabled public String firstName {get;set;} 
        @AuraEnabled public String lastName {get;set;} 
        @AuraEnabled public String email {get;set;} 
        @AuraEnabled public String phone {get;set;} 
        @AuraEnabled public List<RecipientItem> recipient_items {get; set;}
        @AuraEnabled public Boolean isTFAEnabled {get;set;}
        @AuraEnabled public String tfaMethod {get;set;}
    }
    public class RecipientItem{
        @AuraEnabled public String interface_class {get; set;}
        @AuraEnabled public String value {get; set;}
    }
    @AuraEnabled public String firstName {get;set;} 
    @AuraEnabled public String lastName {get;set;} 
    @AuraEnabled public String email {get;set;} 
    @AuraEnabled public String phone {get;set;} 
    @AuraEnabled public String modeOfCommunication {get;set;}  //Email, SMS or Both
    @AuraEnabled public DateTime expirationDate {get;set;} 
    @AuraEnabled public Boolean tfaRequire {get;set;} 
    @AuraEnabled public String tfaMethod {get;set;} 
    @AuraEnabled public Boolean enableTeamFeature {get;set;}
    @AuraEnabled public Boolean bAutomation {get;set;}
    public String requesterFirstName {get;set;} 
    Public String requesterLastName {get;set;} 
    //P2 Feature
    @AuraEnabled public String featureType {get;set;} 
    @AuraEnabled public String featureTemplateName {get;set;}
    @AuraEnabled public Integer containerId {get;set;} 
    @AuraEnabled public String containerRecordId {get;set;} 
    @AuraEnabled public String sTitle {get;set;} 
    @AuraEnabled public String sDescription {get;set;} 
    @AuraEnabled public String sTags {get;set;}  //semi colon seperated
    @AuraEnabled public String sPushFiles {get;set;}
    //Feature Status
    public String p2ContainerItemId;
    public String featureId;
    public String containerStatus {get;set;}
    //is BotDoc SMS and Email Disabled
    public Boolean p2OnlyCreateLink {get;set;}
    public Boolean sendOnlySMSviaBotDoc {get;set;}
}

Under the Wrapper, one need not to set if there is only 1 API Key in use, Last Online need not to be set.
One needs to serialize and then call the GLobal Method GlobalServices.createP2Container(String sWrapper)
