How I can create a code coverage for my code that has many conditions (not for b

Hi, how I can create a code coverage for my code that has many conditions (not for boolean).

Here is my code:
public with sharing class LCC_App_rej_Return_shipment_cApex {
@AuraEnabled
public static void submitFinalApproval(Id recordId) {
//1. RS
if(String.valueOf(recordId).startsWith(‘a0O’)){
update new Return_Shipment__c(Id = recordId, Final_Approved__c = true);
}
//2. VO__c
if(String.valueOf(recordId).startsWith(‘a0G’)){
update new VO__c(Id = recordId, Final_Approved__c = true);
}
//3. RPR__c
if(String.valueOf(recordId).startsWith(‘a0A’)){
update new RPR__c(Id = recordId, Final_Approved__c = true);
}
//4. gProposal__c
if(String.valueOf(recordId).startsWith(‘a0K’)){
update new gProposal__c(Id = recordId, Final_Approved__c = true);
}
//5. Order_Cancellation_Re__c
if(String.valueOf(recordId).startsWith(‘a0L’)){
update new Order_Cancellation_Re__c(Id = recordId, Final_Approved__c = true);
}
//6. Payment_Term_Credit_Limit__c
if(String.valueOf(recordId).startsWith(‘a0N’)){
update new Payment_Term_Credit_Limit__c(Id = recordId, Final_Approved__c = true);
}
//7. Credit_Facility__c
if(String.valueOf(recordId).startsWith(‘a0R’)){
update new Credit_Facility__c(Id = recordId, Final_Approved__c = true);
}
//8. Sample_Request_Form__c
if(String.valueOf(recordId).startsWith(‘a0T’)){
update new Sample_Request_Form__c(Id = recordId, Final_Approved__c = true);
}
//9. Technical_Documents_Request_Form__c
if(String.valueOf(recordId).startsWith(‘a0S’)){
update new Technical_Documents_Request_Form__c(Id = recordId, Final_Approved__c = true);
}
//10. Costing_Request_List__c
if(String.valueOf(recordId).startsWith(‘a0P’)){
update new Costing_Request_List__c(Id = recordId, Final_Approved__c = true);
}
//11. MDR_Declaration_Form__c
if(String.valueOf(recordId).startsWith(‘a0V’)){
update new MDR_Declaration_Form__c(Id = recordId, Final_Approved__c = true);
}
//12. SAF__c
if(String.valueOf(recordId).startsWith(‘a0B’)){
update new SAF__c(Id = recordId, Final_Approved__c = true);
}
}
@AuraEnabled
public static void submitFinalApprovalNo(Id recordId) {

update new Return_Shipment__c(Id = recordId, Final_Approved__c = false);
}
//2. VO__c

update new VO__c(Id = recordId, Final_Approved__c = false);
}
//3. RPR__c

update new RPR__c(Id = recordId, Final_Approved__c = false);
}
//4. gProposal__c

update new gProposal__c(Id = recordId, Final_Approved__c = false);
}
//5. Order_Cancellation_Re__c
if(String.valueOf(recordId).startsWith(‘a0L’)){
update new Order_Cancellation_Re__c(Id = recordId, Final_Approved__c = false);
}
//6. Payment_Term_Credit_Limit__c

}
//12. SAF__c
if(String.valueOf(recordId).startsWith(‘a0B’)){
update new SAF__c(Id = recordId, Final_Approved__c = false);
}
}

}

Kindly help. The coverage not necessary 100%. 75%, and above already ok
