How to invoke COM function (ActiveX) in Octave that takes input parameter?

[nckhrs]

I use Octave 5.1.0 with "windows" package installed (from Octave Forge). I
use it to access COM interface (ActiveX) of a windows app.

I can see the COM functions using:
h = actxserver('MyApp.Application')
com_invoke(h)

I can access COM function that doesn't take any parameter:
com_invoke(h, "GetStatus")

However, for function that takes one parameter, I couldn't find the right
syntax. I have tried these below to no avail:

com_invoke(h, "SetType", 1)
com_invoke(h, "SetType(1)")
com_invoke(h, "SetType", {1})
com_invoke(h, "SetType", ({1}))
com_invoke(h, "SetType[1]")
com_invoke(h, "SetType", [1])
com_invoke(h, "SetType", "1")

I have been searching online, couldn't find any info.

What is the correct way to invoke COM function that takes an input
parameter?
