you can throw that private key into an electrum installation and do it there.
Not a good idea because this will corrupt your key. Just connect the hardware wallet with electrum

I did it through electrum
how does importing the private key to your self-hosted wallet corrupt the key? You can change the transaction air gapped and sign it elsewhere. your private key doesn't change and you can import that to as many wallets as you desire.
.."sign it" was meant to say "broadcast". my bad
