Can't find corresponding options in right-click menu and File Properties dialog box in Visual studio 2019 after install AntlrVSIX

Question

I install AntlrVSIX by nuget. I can find AntlrVSIX in “Extensions” menu. Highlight is also working properly in .g and.g4 file.

But I can't find “AntlrVSIX” in right-click menu and can't set the Build Action under the File Properties dialog box to "ANTLR 4 grammar"
