I cant use Stream labs help

I have followed all the steps to the installation of stream labs. I downloaded the latest release from the release page, created the directory " ~/.config/obs-studio/plugins/ ", but when i write this line of command : " tar -zxvf linuxbrowser0.5.2-obs21.1.2-64bit.tgz -C ~/.config/obs-studio/plugins/ " the output i get from shell is :

tar (child): linuxbrowser0.5.2-obs21.1.2-64bit.tgz: Cannot open: File or folder does not exist
tar (child): Error is not recoverable: exiting now
tar (child): linuxbrowser0.5.2-obs21.1.2-64bit.tgz: Cannot open: File or folder does not exist

Any tips? what should i do??

I don’t understand this. This is GitHub support. Not streamlabs
