Why doesn't it show pictures from bitrix24 without authorization?

Question

Bitrix24

Pictures of goods that are downloaded from Bitrix24 are not visible on the site without authorization on Bitrix24. Although the url of the picture comes up correctly, and if you try to follow the url of the picture, it will redirect you to the Bitrix24 authorization page and if you log in, then here is the picture, what could be the problem? Not all site visitors will be registered in Bitrix24
