There is an app for upgrades: OpenZeppelin Upgrades App for Gnosis Safe
Is there an app for managing roles? https://docs.openzeppelin.com/contracts/3.x/api/access
I’m thinking about digging into https://github.com/gnosis/safe-apps-sdk but don’t want to duplicate the effort.
Thank you for helping 
Hi @marsxr,
I recommend trying out OpenZeppelin Defender: https://docs.openzeppelin.com/defender/admin#custom-actions
It is free to sign up:
There isn’t currently a dedicated action for Access Control so we need to use a custom action.
I have created a simple example: Manage an ERC20 token using Defender Admin and Gnosis Safe
Additional pre-packaged actions are coming up: Defender Release 2020W47
Another great tutorial: Manage an ERC20 token using Defender Admin and Gnosis Safe
I will check it out... Nice 
We want to support a wide range of projects in both topic and scale. For this reason, we are offering grants of between $5.000 and $100.000.
