I can't figure out how to Order by with string_agg - string-aggregation

Question

I have this query (I am using SQL Server 2019) and is working fine (combining Dates and Notes into one column). However, the result I am looking for is to have the latest date show up first.
How can I achieve that from this query?
SELECT ID,
​(SELECT string_agg(​concat(Date, ': ', Notes), CHAR(13) + CHAR(10) + CHAR(13) + CHAR (10)) as Expr1​
FROM(SELECT DISTINCT nd.Notes, nd.Date
FROM dbo.ReleaseTrackerNotes AS nd
INNER JOIN dbo.ReleaseTracker AS ac4 ON ac4.ID = nd.ReleaseTrackerID
WHERE (ac4.ID = ac.ID)) AS z_1) AS vNotes
FROM dbo.ReleaseTracker AS ac
GROUP BY ID
I have tried the ORDER BY but is not working
Here is my table:
CREATE TABLE [dbo].[ReleaseTrackerNotes](
[ID] [int] IDENTITY(1,1) NOT NULL,
[ReleaseTrackerID] [int] NULL,
[AOC_ModelID] [int] NULL,
[Date] [date] NULL,
[Notes] [nvarchar](800) NULL,
CONSTRAINT [PK_ReleaseTrackerNotes] PRIMARY KEY CLUSTERED
CREATE TABLE [dbo].[ReleaseTracker](
[ID] [int] IDENTITY(1,1) NOT NULL,
[AOC_ModelID] [int] NOT NULL,
[MotherboardID] [int] NOT NULL,
[StatusID] [int] NOT NULL,
[TestCateoryID] [int] NULL,
[TestTypeID] [int] NULL,
[DateStarted] [date] NULL,
[DateCompleted] [date] NULL,
[LCS#/ORS#] [nvarchar](20) NULL,
[ETCDate] [date] NULL,
[CardsNeeded] [nvarchar](2) NULL,
CONSTRAINT [PK_Compatibility] PRIMARY KEY CLUSTERED

Use WITHIN GROUP (ORDER BY ...):
SELECT
ID,
STRING_AGG(​TRY_CONVERT(varchar, Date, 101) + ': ' + Notes +
CHAR(13) + CHAR(10) + CHAR(13), CHAR(10))
WITHIN GROUP (ORDER BY Date DESC) AS Expr1​
FROM
(
SELECT DISTINCT ac4.ID, nd.Notes, nd.Date
FROM dbo.ReleaseTrackerNotes AS nd
INNER JOIN dbo.ReleaseTracker AS ac4
ON ac4.ID = nd.ReleaseTrackerID
) AS vNotes
GROUP BY ID;
