function acceptAsset(uint256 tokenId, uint256 index, uint64 assetId) external nonpayable
Accepts an asset at from the pending array of given token.
Migrates the asset from the token's pending asset array to the token's active asset array.Active assets cannot be removed by anyone, but can be replaced by a new asset.Requirements: - The caller must own the token or be approved to manage the token's assets -
tokenId must exist. - index must be in range of the length of the pending asset array.Emits an {AssetAccepted} event.Name | Type | Description |
