)Get raw shares balance (not rebased).
fn shares_balance(env: soroban_sdk::Env, account: soroban_sdk::Address) -> i128Returns the account at the specified index for a given role.
We do not provide a function to get all the members of a role,
since that would be unbounded. If you need to enumerate all the
members of a role, you can use
[AccessControl::get_role_member_count()] to get the total number
of members and then use [AccessControl::get_role_member()] to get
each member one by one.

bounds for the role's member list.fn get_role_member(

e - Access to Soroban environment.This function returns all roles that currently have at least one member.
The maximum number of roles is limited by [MAX_ROLES].
fn get_existing_roles(env: soroban_sdk::Env) -> soroban_sdk::VecCompletes the 2-step admin transfer.

e - Access to Soroban environment.new_admin - The account to transfer the admin privileges to.live_until_ledger - The ledger number at which the pending transfer
expires. If live_until_ledger is 0, the pending transfer is
cancelled. live_until_ledger argument is implicitly bounded by the
maximum allowed TTL extension for a temporary storage entry and
specifying a higher value will cause the code to panic.crate::role_transfer::RoleTransferError::NoPendingTransfer] - If

If the specified ledger is in the past.crate::role_transfer::RoleTransferError::InvalidPendingAccount] -
If the specified pending account is not the same as the provided new
