How to click a RemoteButton

I want to vote for person with specified index after finishing dungeon.I use the code 'RaptureAtkUnitManager.GetWindowByName("VoteMvp").SendAction(1, 3, 0); '

but it only can vote for first player in 'VoteMvp' window.

Can i click a RemoteButton for custom choice? or What params with method 'SendAction' can fill my needs.

'RaptureAtkUnitManager.GetWindowByName("VoteMvp").FindButton(index + 2)'
this can get the specified player button,but i dont know how to activate it.

 

@zzi guru. I tried to solve it, but it didn't work. Could i get your help?

 

Thanks for replying. I'll test it.

 

ulong playernumber = 1;
RaptureAtkUnitManager.GetWindowByName("VoteMvp").SendAction(2, 3, 0, 3, playernumber);
