How to install PGP key for 24.10.0 release builds?

Installing and Using OpenWrt
1

I have worked through the example https://openwrt.org/docs/guide-quick-start/verify_firmware_checksum#linux for release 21.02.0.

I downloaded sha256sums, sha256sums.asc, sha256sums.sig, and the seven OpenWrt One files in https://downloads.openwrt.org/releases/24.10.0-rc7/targets/mediatek/filogic/.

I'm confused about the specific gpg --receive-keys cmd and the particular keys, I tried using:
Public usign key for 24.10 release builds,
Key-ID: d310c6f2833e97f7,
Key-Data: RWTTEMbygz6X95lKDAulctZy3aj15823THXfyrfXgwGbxZlXBd2brNcw.

gpg --keyserver 'keys.openpgp.org' --receive-keys d310c6f2833e97f7
gpg: keyserver receive failed: No data

Any pointers appreciated.
