email when new or updated Post (possible?)

Hi eXperts, I am struggling tryng to create a flow to notify a certain group of users (tipically managers) when a new Post is created for a sales Opportunity inside Dyn365.

I was able to send an email on this event using MS Flows but I need to get the name and the link to the Opportunity inside the body of the email and I could not succeed. Would be great also if possible put the content of the Post inside the body of the email, but not mandatory. Maybe a limit of Flows but don't know.

Is it possible to use the process feature in Dyn365 to do that and how to ?

A question : I assume it works when "I" add a new Post... but what about the reply to my Post ? Is it addressed in the same way or we need a sort of script by an Admin User ? This is because I am not an Admin user but a business unit manager.

Thank you in advance,

Federico
