SyloDataPermissions

getPermissions

Queries the pallet's storage for all available permissions for a given set data ids that have been granted to the specified account.

The response value will include a mapping from each data id to a vector of onchain permissions that relate to that account.It will also include the off-chain permission reference if it exists.

Clients can use this RPC call to avoid making multiple separate queries to onchain storage.
