Is eToro a custodial wallet?

Could you please clarify whether eToro operates as a custodial wallet for its users? I'm interested in understanding if eToro holds onto customers' private keys and manages their funds on their behalf, or if users maintain control over their own cryptocurrency wallets and private keys. Understanding the custodial nature of eToro's wallet service is crucial for assessing the level of security and autonomy offered to its clients.
