Connect with discord sometimes fail.

Some users experience the following problem.

They are trying to checkout a membership plan. On checkout is mandatory to login with discord to proceed. Most of the times that work ok but for some users (that they have discord) the proceed with “Connect to discord” and “authorize discord connecection with the site” they got redirected to the home page like they never authorized or logged in.

Working flow ( User has an active discord account with email )
1) A user is trying to login to our website ( he never logged in or signed up before ).
2) He press “login with discord”
3) New tab to authorize his action to connect with discord
4) User is logged in and redirected to his account
5) On the wordpress side a new user has been created with the information gathered from discord.

Non Working flow ( User has an active discord account only with phone number )
1) A user is trying to login to our website ( he never logged in or signed up before ).
2) He press “login with discord”
3) New tab to authorize his action to connect with discord
4) User Is not logged in and redirected to homepage.
5) On the wordpress side no user has been created because the info from discord does not have a user email thus the user has not been created so as a result he is not logged it

I understand that it makes sense to log you in only if you have email on your discord account, but I think that should not be 100% mandatory for the user.
Or at lease provide an error message that “Please add your email to discord account in order to proceed”

P.S cannot provide any screenshot since there is nothing as error message or something to see ??
