Need help: Dax function to calculate a single value with given filters

Hello!

I have a seemingly very simple problem but I just can not come up with the solution.

I have the following table. It contains example warnings, a date and a value to the respective date:

Now in Power BI I need one measure per example warning that returns the value for the latest date.
For "Test value 1" the value I am looking for would be "6" for 15.02.2021, for "Test value 2" the value I am looking for would be "5" for 15.02.2021 and for "Test value 3" the value I am looking for would be "2" for 15.02.2021.

To calculate this value for "Test value 1", for example, I thought of something like the following measure.

Latest value 1 =
VAR _value =
    CALCULATE (
        FIRSTNONBLANK ( 'Data Warning Test'[Value], TRUE ),
        FILTER (
            'Data Warning Test', 'Data Warning Test'[TestWarning] = "Test Value 1"
        ),
        FILTER ('Data Warning Test', 'Data Warning Test'[Date] = LASTDATE ( 'Data Warning Test'[Date] )
        )
    )
RETURN
    IF ( ISBLANK ( _value ), "No data", _value )

But the problem is that I don't know which DAX function to use inside the CALCULATE function to search for this single value. The FIRSTNONBLANK function here in the example doesn't work, nor does VALUES or MAXX, which I came across while researching. Does anyone have any ideas on how I can write the Measure?
