plotlysetup_offline() can't find plotlysetup.m

[binarycai]

On MATLAB I run :
websave('MATLAB-Online-master.zip', 'https://github.com/plotly/MATLAB-Online/archive/master.zip');
unzip('MATLAB-Online-master.zip');
addpath(genpath('MATLAB-Online-master'));
Then run:
plotlysetup_offline();
and got:
plotly:notFound

Shoot! It looks like MATLAB is having trouble finding the current version
of Plotly. Please make sure that the Plotly API folder is in the same
directory as plotlysetup.m. Questions? Ask https://community.plotly.com/c/api/matlab/

when checking plotlyset_upoffline.m, I run:
which('plotlysetup')
got:
not found 'plotlysetup'

My MATLAB version is 2022b on windows.
How to solve this issue?
