Lemino video download issue

HI

I want to download an unreleased video from Lemino (assuming it will be publicly available in 5 days, but the video has already been uploaded to the server).
I have already obtained the PSSH and license URL for the unreleased video.
The problem is that one required header for acquiring the decryption key is still missing.
This header is generated when the video is actually played, and it includes information like CID, LID, etc., which is sent back through the website's API.
I already have all the necessary information required by that API, but since the video hasn't been officially released yet, the API returns "content contract is out of date".

Is there any way to bypass this time restriction to obtain the header?
There are already people who can download unreleased videos, but I’m unable to ask them.

The header looks like the following

{
"sec-ch-ua-platform": "\"Windows\"",
"acquirelicenseassertion": "ORmpaZCnbEWlc0TmmEadRgAuqviW7FriKo7O1WbAY0dYDdA3r VWlyBIA8GGqJu7cdNv4ZPWkmThbNkkuT+nBmo3szgLQW+V953T kBp2kvgATQ9m0ZO4/JkjgE000i5zBh1+iaJIPz7XC7GPhf5PcH56YnoxNFUlX3ASpZU lAoJehlPeN8OuDN9r1kuSqXEMzWkxINy0+K+eYZrSfcsXI2A6h yaHUyURob9iXBHjlkKW5VgJhakC+oZra40CQe7/Vk0jS8BWHGNOGFyKN8fEV3e8s4pifm8EbXku+1XhXRSZKV4ZTS nW+GYgx49f7lwyYkpciBk9ASHY+CQxXtFNfnDWCRjvxiwZRwBb DfRwDLvmjlxYJSDfL8MD2fe8X7bFt2lFx8fW8qr9x3k1zTo9Sw 4jXvggfwvDcRpAxi3MK8E4tjbL3u+S4paQ+OH3kHJUQJgIlvLZ AfsYsnL4Q3ojA8lb1mUR0hDvgs3E7qUf8nMAwPgN+WCWvyuCc2 mfQn4zuoMm1DyrQOmEyhIYB/qSULO/k57zAPzh4RAfe9ifVd0ZVU4s/fv34YB4Z6YNkdXzfwXMbFrrkFHq5UT0fKA6RywbWRJjsokACX+ DEW26oVfGdyVN0C2toX1q21kva39YbTi/EHlmGK1jgNy9ARx95SS+7OVd8tJ7PvkG9arq4CxwKl22/tAuJ2skzfQ3nFdueQY3hsh4h0x6tO1ClQzvyJtKKxrsDbWxRYr WEdurIvhwfumDc/ORIPme//QyG5SsPz811ThFD/h2cUXJVl5eoXt1d/+VKc73r9Q2yX/ORjDiGGrfybPlUWefDsgv2kTHyn1KyDV6dCUrLZUHldWGyI594 l7Xb6x4DmpPXKDqu89rO9grgj2CY+iofHohqKWY0pPXPcwiZje md4UyEuOLot3SX2r6LhnqlKT2a0qKBjtIKEsE4FH8w7Rm8Yvd+ jg3Z1c58E1LJx2usNFxLR2s8x8Y0ks0CXeQIDnZIlEw4ZXCI+g XbpQdIEQcwi9fbVbKD9JCKGx/akAbJNN0E6HAtkpd3zoc0aPH8nLVTQoW18TL+uhFFFHReSXIKr j7dle4lsEh7SvBx6sQTLRuAQ5XvBxU5GJcBwYixRclAMDjHzDl L08ZWyKHz0ho6tj8e17dt2R091VhXaohXSJlOJDRXSXTVgGNKB sn/9F7KcQvvAAfpbmJujXYuEtn5qN298u766VdMeC9jZpUF/V1qlVyypg==",
