How to write trigger on VisualAccessMetrics? I am not able to view VisualAccessMetrics standardobject in the salesforce edition.

I am new to Salesforce Ecosystem.Can anybody help me solving this :

Contact has a multi select custom field called Role__c which can have values (Surgeon;Nurse;First Assist;Admin;CSR).
Account has a custom field called Total_Score__c which is a number field.
 
Mapping table Role_Score__c looks like this
Role__c         Score__c
Surgeon         10
Nurse           5
First Assist    10
Admin           0
CSR             20
 
When a contact is created/updated, get total score of all the UNIQUE roles that exist on all the contacts of the account.
 
Ex: Account 1
Contact 1 with roles Surgeon;Admin
Contact 2 with roles CSR:Admin
On Account 1 we should store the value as (10 + 0 + 20 = 30) because we only have 3 unique roles

I need with proper explanation :

Did anyone have written Platform Developer I in the recent times like last week or 2 weeks ago? If so I wanted to ask whether you have faced questions related to lightning(aura) and Lightning Web Components(LWC)? I heard from Feb, the PD1 question pattern is going to change and will focus more on lightning and LWC. Please guys respond.

System.debug('List is' +candList);
List<Job_Application__c> jobList=candList[0].Job_Applications__r;
