A .csv generated by Krita through File > Export

SUMMARY
The Krita documentation says it both export and import the .csv animation format from TVPaint.
https://docs.krita.org/en/general_concepts/file_formats/file_csv.html?highlight=csv
It does not seem possible to import the .csv animation.

STEPS TO REPRODUCE
1. I've attached a .csv file generated by Krita.
2. Choose File > Open
3. Navigate to .csv and choose open

--ALTERNATIVE METHOD--
(I didn't really expect this one to work, but thought it could be possible)
1. File > Import animation frames
2. A dialog opens for adding images. I choose Add Images... and select the .csv
3. Click OK


OBSERVED RESULT
I get the following Error message alert:
"Could not open file:\\\Krita_Animation_Test.csv.
Reason: The file format cannot be parsed.."

EXPECTED RESULT
A Krita project opens with the same layer structure and frame timing as when exporting the .csv.
