Activity $1($Unlock a coded message$)$

Doctor Strange is in deep trouble. He is being pursed by Thanos and is presently hiding in a secret location to escape from being captured by him. He needs to send messages to two of his comrades Thor and Captain America, to tell them about his situation and whereabouts. As such, he composes his first message by replacing each letter in the message by a number according to the code in Table $1$ below.
