Cant see OpenFL extension in Animate

I dont know whym but after install the OpenFL extension for Adobe Animate CC, I cant find the export panel.
I use macOS High Sierra 10.13.2 (17C88)
Adobe Animate 2017.0.1 Release - Build 16.0.1.119

We should be up to 1.0.1, can you try using the Adobe add-ons site (https://www.adobeexchange.com/creativecloud.details.12931.html) then allowing Creative Cloud to install it? You may need to uninstall the version you have first
