Show FormCraft form on page open

I am using WordPress FormCraft plugin on my site. I created a form and got the form short embedded code

[fc id='4'][/fc] 

I want to show this form when the user opens the page.

Can anyone tell how can approach this?

I also try in Page Editor I got an option to add form it generated below code for me.

[fc id='4' type='popup' button_color='#4488ee' font_color='white'][/fc]
