I need to upload facebook reels with api but show this error

{
“error”: {
“message”: “(#200) Subject does not have permission to post videos on this target”,
“type”: “OAuthException”,
“code”: 200,
“fbtrace_id”: “A0vPpH6U1wfZ9o_4cMqmEH3”
}
}

I have done everything as per documentation all permissions are given eg
pages_show_list
pages_read_engagement
pages_manage_posts

and also i have page admin access (full control )
