Is there an old version of Daedalus that can connect and work with the Nano X ADA app v2.0.3 (dated from around Aug 2020)?

We have a Nano X that secures large ADA funds (~$100k value), that has the ledger ADA app v2.0.3 (from around Aug 2020). Unfortunately the ledger seed phrase is lost, so we do not want to update the ledger firmware (risk of reset and losing all the funds).

We tried connecting to the Nano X with the current version of Daedalus, and it will not connect to the ADA app on the ledger. We tried running Daedalus as administrator, no luck. It connects well with Ledger ADA app 2.4.1 (on a slightly more recent Nano X), but no luck with v2.0.3. I also tried Adalite, no luck either (says the ledger app is too old).

We tried with Daeladus 2.3.0 (from mid 2020), but it cannot connect to a ledger (does not have the functionality).

The first version of Daedalus that has the function to connect to a ledger is I believe 3.0.0? Do you think it will support this ADA app v 2.0.3 on the ledger?

I found that the first version that works with ADA app 2.4.1 is Daedalus 4.0.3. I am just not sure which of the 3.x versions will support ledger ADA app v2.0.3...

Does anyone know?

It would be possible to export the keys from the Nano X on the cli. But normally an cardano-app update or a firmware update does not require to reenter the seedphrase on the ledger.
