Import Flight Plan

I use with satisfaction the new MSFS In-Game Panel. At this moment I would like to import a flight plan not from SiemBrief but from other sources. When I click on the bottom “+New flight” It appears “Manual input”, "From SimBrief and “From file”. I click on “From file” and appears a bottom “Select flight plan” with the spacification Import from file but I’cant do anythin or chois. Could you help me please
