What was the point of Israel attacking Hezbollah pagers and walkie-talkies?

What exactly was Israel's strategy in detonating explosives inside thousands of Hezebollah pagers and walkie-talkies? To prove they could do it and make Hezbollah feel vulnerable? Or was it a precursor to a full-scale war with Hezbollah? Or was it really a message to Iran? Or was it a way of telling Hezbollah to back off helping Hamas in Gaza and to move back from the border with Israel and stop launching rockets at Israeli towns and cities? The pager/walkie-talkie explosions killed three dozen people and injured thousands more. Was this Israel's intention, to kill and maim and to do it in a way that made the whole world think, Oh my God, this is the way war is going? Of course, nothing, absolutely nothing compares with the atrocities and rapes and hostage-takings carried out by Hamas on October 7. But this latest form of warfare against Hezbollah leaves a very uncomfortable feeling somehow. It was dastardly, it was brilliant espionage. But what was the real point of it all? Killing people in markets and in the streets and in their homes with technical wizzardry. What really is the message Tel Aviv is sending out? Will it help to bring the war in Gaza to an end? Surely not.
