Enable Internet Access for Your Fleet, Image Builder, or App Block Builder in Amazon WorkSpaces Applications

When working with IPv6 only subnets, default internet access cannot be enabled. You'll need to set up an Egress-Only Internet Gateway and configure route table to allow outbound internet traffic. For more information check the steps. You also need to enable auto-assign IPv6 addresses for your subnets. The Egress-Only gateway handles outbound internet traffic only so if you need inbound access, you'll still need a regular internet gateway. You can find more details about this in egress only internet gateway documentation. Ensure appropriate security and networking controls exist to prevent accidental inbound/outbound access for your subnets.
