Modal Popup window in Appian for Chat bot requirement

Hi Team,

Is there any way to open Modal pop up window in Appian , our requirement is to open chat bot like popup on the right hand side of the page when user clicks on button. 

The Record Relation way I have already tried and its opening on the entire page as popup, and also have tried the show hide way of showing interface.

besides these two ways is there any other way of showing popup window in Appian for chat bot.

Thanks

Bihitak
