VSTO(.vb) uses EXCEL built-in function Match() exception

Question

Project is VSTO Excel Add-in (vb), when using EXCEL built-in function Match(), an exception occurs.

Imports excel = Microsoft.Office.Interop.Excel

Function match_out ()
    Dim index As Integer

    'The build error is here
    index= excel.WorksheetFunction.Match(1, {2, 1})
    
    return index
End Function

I want output result:

index = 2

but feedback:

error:BC30469 Reference to a non-shared member requires an object reference
