So I tried to cheap out and choose the lowest fee option on Trezor. Transaction has been stuck for more than a week. Unfortunately, I can't go by the RBF option and transaction accelerators are too expensive.

However, what I realized is that Electrum still reflects my original balance before I posted the transaction. Can I then do the following to unstuck the transaction?
(1) Go to Electrum and by coin control (https://bitcoinelectrum.com/how-to-spend-specific-utxos-in-electrum/) send the same transaction but with a higher fee.
(2) I would be spending from the same address as my stuck transaction ie. address starting with 3L1Y (https://i.imgur.com/f8oWW2O.png)

Question 1: Does this work?
Question 2: Do I have to send the exact same amount as my previous transaction?
Question 3: Anything I should be aware of prior to doing this?

Thanks!
