Python Selenium - copy.paste not work in headless mody

Question

I try to create script with Selenium, that will log in into web version of Bitwarden, then upload file that exist somewhere in my OS. Everything work without headless mode, but not with headless mode. I don't have any errors, but functions provided by that checkbox not work. Checkbox is responsible for generate and copy link to download uploaded file to my account. I generated screenshot in headless mode after checkbox, and it is clicked, so not work function provided by checkbox.

Any ideas, recommendations? I repeat, without headless mode, everything is OK. My link is copied. I think, it could be a problem with some limitation of headless mode. Nevertheless, is any way to bypass this, if limitation could be true? Sorry for any mistakes, English is not my main language, but I work on it.
