Can not Import data from TeslaFi

[choke55]

My Teslamate are running fine - but now I would like to import all my historical data from TeslaFi.
I have created the csv file for one month from Teslafi - but I can´t import it.
As I understand the main Teslamate window should be able to pick up the file when it is stored in /opt/app/import
But where in the @docker/ ??
Have copy TeslaFi112022.csv to @docker/opt/app/import - but nothing happens after restart of Teslamate in docker.
Anyone who have done this and can point out where shall the csv-file be?

Thanks
