Site invitations
Undo declining a site invitation
Puts a declined invitation back to pending, until the same expires_at. Only a decline can be undone. Undoing a pending invitation that can still be answered returns it with 200. An invitation the list leaves out, because its sender has left the company or no longer owns the site, is closed as superseded instead, and the answer is 422 superseded with error.details.reason not_owner. Past expires_at it answers 422 expired, after the owner withdrew it 422 revoked, when superseded 422 superseded, and once accepted 409 with error.details.error accepted.
A bearer with write access only: a request on the cookie mount is refused with 403, with or without an X-Fluid-Member-Site header, and so is a member JWT, or a portal JWT minted read-only. It answers 404 while member sites are not enabled for the member’s company.

}Authorizations
A member credential in the Authorization: Bearer header: a member
session JWT, a portal JWT whose login is linked to a membership in
that company, an opaque member token, or a verified One Auth identity
access token. The credential alone identifies the member and company.
Member session JWTs, and portal JWTs the server minted read-only, are
refused with 403 on every write.
Path Parameters
Id of one of the member's site invitations.
Response
The invitation, pending again.
One site invitation.
HTTP status code (mirrors the response status line).
One invitation to a site, as the member it invites sees it. Accepting it shares the site with the member; the invitation itself grants nothing.
