hi there, i have a some questions here, I'm using the electrum-ravencoin wallet, i try to use my ledger Nano X hardware wallet to connect it, i have backed up my seed phases safely somewhere else and chosen the BIP39 format. if i delete all the electrum-ravencoin wallet files and folders in my computer (or i try to restore it from another new computer), will i be able to get everything back just by these seed phases? do i need keep the original ledger device(or i could just buy a new one then put the seed phases in?) or do i need backup some electrum-ravencoin wallet files in order to make sure i could restore everything? thanks for your reply.
