I am running an older wallet with a BIP39 seed phrase on Electrum 4.5.2. I was able to load the wallet from a file and see most of my transactions. However, when I try to see the seed phrase the option is greyed out. Why is this and/or is there a way to see my seed?

I'd like to get my phrase and import it into another wallet and am traveling ... away from my hand-written backup. Appreciate any help
