.This process involves two APIs:

getSignatureForOfferApproval: This API retrieves the offer details required for the token owner to approve the offer. It initiates the process of accepting the offer.
acceptOffer: After the front end successfully processes the offer acceptance transaction, confirm the transaction by calling the acceptOffer API. This finalizes the acceptance and records the transactional activity.
