Line Contact Key Updates in Group Connect

our requirement is we need to send a message when active in LINE account and should not send when not active using journey builder.

In the journey, before we send LINE message we check the LINE status in Group Connect subscription data view table matched with the contact key and in our entry source data extension we use the same contact key relates with subscriber key.
We found when member who already in Journey, blocks the LINE account, the LINE ID record got removed in GroupConnect and again synched back with new Contact key if they unblock LINE account.

In the above scenario, how can we check the line status with the old contact key when the user unblocking the LINE account in journey builder while in the middle of the journey?
Could you please help on the above
Thanks
