How to make a checkpoint commandblock but make it only go once

I am trying to make a map and I have a command block to detect when the player is on a gold block and a chain command block to say the message in chat but it spams it until I get off the gold block, Is it possible to make so it’ll only say it once? (The repeating command block command is: execute as @a at @s if block ~ ~-0.35~ gold_block run spawnpoint @s ~ ~ ~ -90)
