unable to link onedrive for business

[Administrator]

I am unable to link my onedrive for business there is no option for searching or link the onedrive, i can only use already uploaded file in my confluence page.

I have had to upload files rather than link to onedrive, I think this may be down to our business security settings. Our onedrive is only accessible to people within the company, so confluence in effect is an external user.
