Just use OCR

import base64

data = "7ZSM66CI7JZ07ZW07KO87IWU7ISclOynhOyLrOycvOuhnCDQsJDSgqzrk5zrp3ri4jri6QuCuuLpoydjCDsnpHtkjo5nLzroZwg65iQlOunjOuCmOu1kCDsiJgg7J6l6rKMIOqOmOq4sOuIvCwg7KeE7lus7Jy866GcIOq4sOybkO2vqeuiLOuLpC4="
decoded_bytes = base64.b64decode(data)
decoded_text = decoded_bytes.decode("utf-8")
print(decoded_text)

Exactly what the topic says :D
