I now have a tab in the IDE with debug_custom.json:

{
	"name":"Arduino on ESP32-S3",
	"toolchainPrefix":"xtensa-esp32s3-elf",
	"svdFile":"debug.svd",
	"request":"attach",
	"overrideAttachCommands":[
		"set remote hardware-watchpoint-limit 2",
		"monitor reset halt",
		"monitor gdb_sync",
		"thb setup",
		"c"
	],
	"overrideRestartCommands":[
		"monitor reset halt",
		"monitor gdb_sync"
	]
}
