Orfeo Tool Box Provider not available in QGIS 3.36.0 Mainhead

I want to use Orfeo Tool Box within the QGIS Interface. I tried to follow the installation guide in the CookBook. I got an error so I reinstalled QGIS in the newst version (QGIS version 3.36.0-Maidenhead; OS version Windows 10 Version 2009). I then tried to install it again but the Orfeo Tool Box Provider isn't available in the "Plugins/Manage and Install Plugins.." toolbar.
