Is it possible to change embedMode without creating a new view(and have it work properly)?

hi! I'm still learning on how to use the view sdk. however, I've encountered a problem.

Everytime when I want to switch the embedMode, I have to create a new view object in my js script to have it work properly, otherwise. the config will just be screwed up and the embed mode switch will be looking weird. 

so I just wanna ask here, do we need to create a new view everytime we want to change the embedMode? or is it possible to just:

viewobj.previewFile({
        content: {...},
        metaData: {...},
    }, {embedMode:"anything I want"});
change it like this and have everything work correctly? because I couldn't get it working.
