Hi, is it possible for an api user to have granular access so that he can only transfer/view the assets from one vault? How could this be accomplished? Thanks ---

Would TAP (Transaction Authorization Policy) help me achieve this? in the sandbox, I cannot configure it. ![image](https://us1.discourse-cdn.com/flex015/uploads/fireblocks/original/1X/d89b05347425d2c13aea77c4cb470efb9e7dca2f.png) ---

I tried to modify the ‘profile \> quorums \> Change the TAP’ section enable TAP modification, but an error is thrown: ![image](https://us1.discourse-cdn.com/flex015/uploads/fireblocks/original/1X/569db05b54a517e1ab70bb458f5c49268b4e3416.jpeg)
