Looking at the documentation at this link Submit Mapping Request I can see that a Polygon mintable asset requires that:
The mint function on the root contract can only be called by the corresponding token, PredicateProxyAddress
But what if I want to give the same grant to other addresses? In my use case I would like that the tokens can be minted in both chains (Ethereum Goerli/Mainnet and Polygon).
Granting the role (at deployment time embedding the code inside the constructor or in a later stage, sending a transaction) is an impediment for the mapping and/or prevent the bridge to works properly?
Any clarification or hint is really appreciated. Thank you!
