Our Braintree extension is part of core Magento / Adobe Commerce under the VBE (Vendor Bundled Extensions) Program since v2.4.0. So you don't need to install our extension separately on any Magento / Adobe Commerce v2.4.x versions.
Magento / Adobe Commerce has stopped support for v2.3.x since September 2022 that's why we also have discontinued our support for our Braintree extension which was supporting only v2.3.x.
Magento / Adobe Commerce already has removed our Braintree Payment extension from the Marketplace as it was only supporting v2.3.x
