/seed command not working as expected

/seed only works if you're the person entering it.

/execute as @a run seed does not have the seed show up in everyone's chat, rather, it shows up in your chat the number of times equal to the number of players online.

/seed or /execute as Drewza run seed executed from a datapack or command block doesn't show anything (my username is Drewza)

If this is the intended behavior, are there other methods of getting the seed to display in everyone's chat?
