Foreign stock sale - no 1099-B - how to upload documents?

After I manually filled out my foreign stock sale as though i had 1099-B, the next step shows that uploading documentation of the sales summary is required by IRS. 
As the foreign securities institution and foreign regulations are not required to have an equivalent 1099-B form, I retrieved all the sales in 2023 from the report the institution provided. However, other than the sale numbers/dates, this document is in foreign language. Is this ok to upload as is? Also, am I required to upload spreadsheet/documents on how the calculations are made for the capital gain or loss?
