Apex Sharing on Selected Records Using Developer Console

Apex Sharing for Standard Case Object . For every Standard Object we need to append Share keyword. Like for case apex sharing object will be CaseShare

  List<Case> CasesList = [SELECT ID FROM Case];
    List<CaseShare> csShareList = new List<caseShare>();       

        for(Case csInstance:CasesList){ 
            
            for(User usrInstance:[Select ID FROM USER WHERE IsActive = TRUE AND ProfileId ='00e5C000000DeBi']){
                
                CaseShare csShare = new CaseShare();//this should be in for loop
                csShare.CaseId  =csInstance.Id;
                csShare.UserOrGroupId = usrInstance.Id;
                csShare.CaseAccessLevel = 'edit';
                csShareList.add(csShare);
            }
        }
    Insert csShareList;
