rejectNetworkFirewallTransitGatewayAttachment
inline suspend fun NetworkFirewallClient.rejectNetworkFirewallTransitGatewayAttachment(crossinline block: RejectNetworkFirewallTransitGatewayAttachmentRequest.Builder.() -> Unit): RejectNetworkFirewallTransitGatewayAttachmentResponse
Rejects a transit gateway attachment request for Network Firewall. When you reject the attachment request, Network Firewall cancels the creation of routing components between the transit gateway and firewall endpoints.
Only the firewall owner can reject the attachment. After rejection, no traffic will flow through the firewall endpoints for this attachment.
Use DescribeFirewall to monitor the rejection status. To accept the attachment instead of rejecting it, use AcceptNetworkFirewallTransitGatewayAttachment.
Once rejected, you cannot reverse this action. To establish connectivity, you must create a new transit gateway-attached firewall.
