It is not clear what `params` does, or how to access to it

I don't use React Router, and I'm trying to use the params in order to show a modal.

But the url in Linking.getInitialURL is always null

const url = await Linking.getInitialURL();
checkUrl(url);

// ...

  const checkUrl = url => {
    try {
      if (!url) {
        return;
      }

      const { hostname, queryParams } = Linking.parse(url);

      if (queryParams && queryParams.href && queryParams.href.includes('about-to-remove')) {
        Alert.alert(
          i18n.t('Tell me what happened'),
          i18n.t('Send me an email to my personal account, and tell me what I can improve') +
            ': brodanoel@gmail.com',
          [
            {
              text: i18n.t('No'),
              onPress: () => {},
              style: 'cancel',
            },
            {
              text: i18n.t('Ok, sure'),
              onPress: () => {
                Linking.openURL('mailto:brodanoel@gmail.com?subject=NoFilter feedback');
              },
            },
          ],
          { cancelable: false }
        );
      }
    } catch (error) {
      Sentry.captureException(error);
    }
  };

I was expecting to access to params in hostname or queryParams, but nop... URL is always null (at least, in development build)

Consider looking over how the Expo Router code works to better understand the params functionality https://github.com/EvanBacon/expo-quick-actions/blob/202b148a76c96b20292c3fc6ef7dde1bc7e6b655/src/router.ts#L28

Unlike Expo Router, standard native apps don't enforce that a URL be present at all times. This means you may need to add some state to account for the edge cases where the app was not launched from a URL.

@EvanBacon so, let me check if I understand it: you are telling me that when the app is launched from the Actions, it is not consider "from an URL", thus, I have to handle this other case.

Is there a name for this "other case"? So I can look for some documentation.
