Map firewall endpoint in a route table

When you create a was network firewall it creates the endpoints in the subnet by default. How do I map firewall endpoint in a route table?

resource “aws_route_table” “tgwRT1” { # Creating RT for tgw Subnet

vpc_id = aws_vpc.vpc_main.id

route {

cidr_block = “0.0.0.0/0” # Large cidr range

vpc_endpoint_id = endpoint_id

}

tags = {

Name = "euw1-firewalltgw-subnet-rt"

}

}
