Possible to have the fullscreen gallery already open when the page loads?

Hi there,

I was wondering if it is possible to have the fullscreen gallery already open when the user clicks on the page?

I’m familiar with Galleria galleries already, can we use the original documentation to make this happen using javascript/jquery? ie. on eof these options: https://docs.galleria.io/category/28-option-list?sort=name

Any help appreciated.

Cheers
