If I remember correctly, I heard it on Radio 4 or LBC News, but this article is the first I stumbled on that makes reference to it.

It looks to me that France wants these migrants to be relocated over the whole of the EU, not just in France.
[EXTRACT]
…it appeared on Monday night that France is seeking an EU-wide agreement that could involve the return of Channel migrants to the continent.
Mr Darmanin called for a "balanced" accord that would offer "real solutions" for dealing with organised trafficking networks that are often spread across France, Belgium, Germany and other countries. He insisted it could not be with France alone, but with all of the EU.
"We do not want a unilateral agreement," he said after a meeting chaired by Mr Macron. "An agreement would set the framework for co-operation between Britain and bordering countries on immigration issues that were not negotiated at the time of Brexit."
The deal set to be proposed by France could include ways to ensure unaccompanied minors can safely reach Britain to rejoin their families instead of putting themselves at the mercy of traffickers, Mr Darmanin said. Britain has said the quid pro quo would be France taking back migrants.
