Sentry One on Azure Data Studio

I followed these instructions to install:

https://sqlperformance.com/2019/08/sentryone/plan-explorer-extension-azure-data-studio

I made sure my version is greater than 1.9.0 (mine is 1.43.0) 

I installed .net 2.1 for MacOS

When I try to toggle on the sentry plan explorer I get this error :  'command 'planViewerAds.showInPlanViewer' not found". Does anyone know what this error means?
