Set Bubble App as Subdirectory of Existing Site (Wordpress)

Has anyone successfully set up a Bubble app as a subdirectory of an existing website hosted elsewhere?

i.e., the URL would be www.website.com/app

I’ve read it could be possible using a reverse proxy.

Otherwise we will have to use iFrames or simply host the app as a subdomain (i.e., app.website.com), but neither of these options are ideal for SEO or user experience.
