When you use a hardware wallet, you can write the seed and initial address, then reset the hardware wallet and restore with the seed. Check to see if it's the same address. When you're done with it, you won't have to worry about damaging your hardware wallet.
Similarly, when you use umbrella to build a lightning node, you can open a channel with a very small amount of funds (10000~50000 sats). Back up your seed and channel.backup , then delete and reinstall your node, using the seed and channel.backup to restore your funds. Although there is a very small probability of operational errors and loss of funds. But experience is priceless. Once you have practical experience, you will not panic at critical moments.
