My girlfriend hasn't received an invite in about two weeks

[BenisPoy]

good morning! my girlfriend has been waiting for either my invite or of one of two other friends' invites to arrive for 12 days now and nothing has appeared in either of these links:

• https://store.steampowered.com/account/playtestinvites
• https://store.steampowered.com/account/gatedaccess

we did a bit of research and we found this thread https://forums.playdeadlock.com/threads/my-friend-cannot-accept-receive-an-invite-to-deadlock.85768/ where someone mentions joining the Discord and a moderator helping them invite their friend if they rejected an invite before, which she did. someone she didn't know very well invited her over a year ago and she rejected the invitation, i confirmed by looking with her at her email history
i joined the discord yesterday and asked about this there and someone told me to post in the forums for help. is there a specific process i should go through to get her an invite at this point? thank you!
