command Open not recognized on Win10

[HiD3f]

Hi, huge user of PocketCasts, but it's a pain to open the browser to use it. Had the idea to look for someone who created an Electron version of it and found your work. Thank you !!
The problem is that I get the following message when I run the last command :

C:\Users\username\pocket-casts-electron>open PocketCasts-darwin-x64/PocketCasts.app/
'open' is not recognized as an internal or external command,
operable program or batch file.

Since you seem to be using it on MacOS it might be due to OS .
I found a similar issue on another Electron app repo coryhouse/react-slingshot#350

"Since the commands node_open uses are dependent on the OS being used, the package.json has to be changed to use 'start' on Windows rather than the 'open' one that is in the package.json. "

I don't know how to do that, it would be great if someone could please.

Thanks
