Is a transcript enough?

Hi everyone, I’m an applicant from a country where we graduate high school after a taking a leaving exam. I graduated in 2018 and have been given a sheet that summarizes the grades I have.
Now that I want to apply to universities, I lost that paper and the principal of the high school I attended told me that he couldn’t find it in the archives, so he couldn’t upload it. However, all the information contained in this sheet is also available on the transcript. Should he just apply the transcript + translation twice, or is the lost sheet necessary?

Thank you very much.

Clarification that I feel is needed:

The sheet I got after graduating is not the transcript, it’s a sheet that summarizes the grades I got specifically in the leaving exams. That same information is also available on the actual transcript.
