s_eventIdToTokenIds: store all tokenIds(array of uint256) related to particular eventId(string).
s_eventIdToAccessLevels:store all accessLevels(array of Strings) related to particular eventId(string).
s_tokenIdToTicketPrice: maps ticketPrice(uint256) to particular tokenId, default price for any tokenId is Zero.
s_tokenIdToWhitelist: maps token IDs to a boolean indicating whether they are on the whitelist.
s_tokenIdApprovals: maps token IDs to approvals granted by specific addresses (only event manager needs to approve).
s_collectedAmountForEventId: maps event IDs to the total collected amount (for paid tickets).
