Tableau Fixed LOD to PowerBI

[dogt1225]

I have a dataset with all requests in a buisness. 
There can be 1 or more [Order] within a [Request]. And 1 or more [Appointment] within an [Order]. After each Appointment is completed a [Score] of 0-5 is provided by the customer. Not every customer will provide a score, hence some of the nulls. 
Example dataset provided below:

Request	Order	Appointment	Score
1234	1001	App - 1	4
4567	1002	App - 2	5
4567	1003	App - 3	5
6789	1004	App - 4	1
4321	1005	App - 5	4
6543	1006	App - 6	3
6543	1007	App - 7	5
6543	1008	App - 8	5
9123	1009	App - 9

On the  [Request] level, I am looking to calculated the count of [Request], where [Score] = 4 or 5. Below is the calcualation for Tableau, how would I convert this to PowerBI?

{ FIXED [Request]: max(IF [Score] = 5 then 1
ELSEIF [Score]= 4 then 1
else 0
END)}
