[DOCS] Linkedin OAuth link

Hi there, we have been trying to setup the account in Linkedin:

Add the URL https://.firebaseapp.com/popup.html to the OAuth 2.0 > Authorized Redirect URLs of your LinkedIn app.

the issue is the url is not being accepted, we got the application id and the final looks like this:

https://1:312666799144:web:b7f11067d1fc976ded.firebaseapp.com/popup.html

when we try to submit it in the OAuth 2.0 settings in Linkedin we cant save with that url.

would have any suggestions?

Thanks

Start by reviewing the LinkedIn OAuth setup described in the issue, especially the Firebase popup redirect URL and LinkedIn's Authorized Redirect URLs setting. Confirm the accepted redirect format and update the relevant documentation if a correction is identified; done means the instructions provide a URL that can be saved successfully.
