Hello Charlotte,
Not much documentation available regarding this. I tried to list the steps in detail, play around and sure you will be able to complete your tasks.
1) Login to https://flow.microsoft.com/
2) Create New Flow From Blank
3) Click Create from a blank
4) Find the trigger "When a record is created" Common Data Service
5) Select your Talent Environment
6) Select Entity "Job Application Activity Participant" [you will find fields Job Application Activity, Is Recommended & Overall Comments here]
7) Click New Step, Add Action -> Condition
8) Add condition, Feedback Status Reason value = Completed
9) If yes, Add Action -> “Get Record” common data service, Job Application Activity [Filter: Job Application Activity = xx, you will find field Job Application]
10) then Add Action -> “Get Record” common data service, Job Application [Filter: Job Application=yy, you will find field Job Opening]
10) then Add Action -> “List Records” common data service, Job Opening Participant entity [Filter: Job Opening=zz && msdyn_role=2 which is Hiring Manager, you will find msdyn_WorkerId]
11) then Add Action -> “Get Record” common data service, Worker [Filter: Worker=msdyn_workerid, you will find the full name & email address]
12) Send Email
Similarly, you can perform your second task.
Best
