Creating a custom shortcut

Hi Guys,

I have a dumb question about shortcut.

I have an App on my iPhone to control the opening of my front gate.

When I'm arriving at home, I need to open the App, click on one button to open the gate.

I would like to automatise this operation with Siri such as " Siri, open the gate"

This 3rd party App is not listed in Shortcut app, this is not compatible with "HomeKit" nor Alexa...

I was wondering if the Shortcut App would allow me to create a script telling it that it need to click at a specific place to active the gate opening.

Any chance I can fo that with Shortcut ?

Thanks for your valuable help ;-)
