Find Minecraft Underwater Temple?

Just try to find a temple in my Minecraft world. Have already searched in a radius of about 2k blocks and still not found. Are there any special biomes where they appear or have they become so rare?

You have to search for a temple in a jungle
For a underwater temple you have to in the biome "deep ocean" in German: Deep ocean or something

Command / locate and then tab with the appropriate search then enter

Yes, I've searched several oceans but never found a temple

That would be cheating.

Give the command: "/ locate Monument" then there would have to appear coordination. Click on them, press Enter and get teleported there.
