Full Screen Button will no work in an iframe or in a new custom url

[UOTLeop]

Thank you for your amazing package which add powerful function to polish the leaflet package. Currently, we meet a small problem for the fullscreen button. It work perfectly in the local machine as well as in the original url when we deploy the data on to shinyapp.io. But the full screen button will not work when we open the page in an iframe or deploy it into our custom url following the guide https://shiny.rstudio.com/articles/custom-domains.html. Is there a possible way to fix that

You need to set the pseudoFullScreen to TRUE in the options.
