In what scenario will messageID not be set? It would be easier to understand how this function is used if you included it in the same diff where you introduced the first usage

It is not currently used anywhere, but I use it locally to test it (tooltip-utils.js):

function useMessageEditAction(
  item: ChatMessageInfoItem,
  threadInfo: ThreadInfo,
): ?MessageTooltipAction {
  const { messageInfo } = item;

  const canEditMessage = useCanEditMessage(threadInfo, messageInfo);
  const editMessage = useEditMessage(messageInfo.id);

  return React.useMemo(() => {
    if (!canEditMessage) {
      return null;
    }

    if (item.messageInfoType !== 'composable') {
      return null;
    }

    const buttonContent = (
      <SWMansionIcon icon="edit-1" size={18} disableFill={false} />
    );
    const onClickEdit = () => {
      editMessage('Test ' + new Date().toLocaleString());
    };

    return {
      actionButtonContent: buttonContent,
      onClick: onClickEdit,
      label: 'Edit',
    };
  }, [canEditMessage, editMessage, item]);
}

Scenario: Here sometimes messageInfo.id can be sometimes undefined, and I cannot use condition here, before calling the useEditMessage, because of React Hook "useEditMessage" is called conditionally error.

lib/shared/edit-messages-utils.js
42–44 ↗	(On Diff #24061)	Why are we doing this? What does it achieve?
38		Should we instead have an `invariant` here? From your code snippet, it looks like `useCanEditMessage` should prevent the callback from being called if `!messageID`
