migrating from the NGINX Ingress Controller to NGINX Gateway Fabric -concern on cookie session

[anuragnp1997]

Our goal is to replicate specific session persistence behavior for a production application
these are the annotations which we use in our nginx ingress
nginx.ingress.kubernetes.io/affinity: cookie
nginx.ingress.kubernetes.io/session-cookie-name: WebAppName
nginx.ingress.kubernetes.io/session-cookie-expires: 172800
nginx.ingress.kubernetes.io/session-cookie-max-age: 172800

can I get these on Gateway API
we are corrently using NGINX Gateway Fabric with CRD version v1.4.1
how can I achieve these on Gateway API
