format request to send dynamic link push notification nodejs - node.js

Question

I am attempting to add dynamic links to push notifications so users tap them and open to a specific app page. I have been following the documentation and the links do not open to the page they should when I tap the push notifications but when tested in the browser the links do open to the correct page. From what I have read, there are 2 possible solutions depending on the version of firebase the project is using. The older "way" is to add a click_action property to the apns payload object, the newer way is to create a webpush object with the fcm_options property set to the value of the link. Neither of these options seems to work regardless of where the objects are placed in the request. Is my request formatted incorrectly or am I possibly missing something? Below is the current request:
const [title, body, deepLink] = titleAndBody;
let accessToken = await getAccessToken();
accessToken = "Bearer " + accessToken;
const options = {
method: "POST",
url: URL,
headers: {
Authorization: accessToken,
"Content-Type": "application/json",
},
body: JSON.stringify({
message: {
token: fcmToken,
notification: {
body: body,
title: title,
},
webpush: {
fcm_options: {
link: deepLink,
}
},
apns: {
headers: {
priority: "10",
},
payload: {
//click_action: deepLink,
aps: {
badge: 0,
mutable_content: 1,
},
},
}
},
}),
};```
