I searched many official documents about bot framework. However, I did not find such information about the scope of bot’s permissions.
Then, I checked some official bots’ permissions, which mainly related to the Teams itself, not user machine. The following image is just for your reference.
Meanwhile, as we are mainly responsible for general issue of Microsoft Teams, your question which is involved in development is not in our scope. I would add the office-teams-app-dev tag. Hope you get better response.
