pagoda2WebApp_readStaticFile function does not work

[Auryllius]

Hello, I'm using Pagoda2 ver. 1.0.12 and able to create the web app through the tutorial provided here. However, when I want to work on the bin files (which were also created by using pagoda), I cannot upload the files to the R environment. Specifically, I'm trying to use pagoda2WebApp_readStaticFile function and when I try to use this function, I get this error message: pagoda2WebApp_readStaticFile' is not an exported object from 'namespace:pagoda2'

p2web <- pagoda2::pagoda2WebApp_readStaticFile(filename=`"**/PATH TO BIN FILE**"`)
pagoda2::show.app(app=p2web, name="app",ip= "127.0.0.1")

Since I can't load the bin file to the environment, I can't use the show.app function. How can I load the bin files? Thanks in advance.
