I'm a newbie who bought a CoinKite ColdCard and downloaded Electrum 4.1.5 Portable to my desktop.  I then transferred my bitcoin from Kraken, Voyager and Cash App to Electrum and it worked!  Now my issue is with using ColdCard Offline with Electrum.  ColdCard says to create skeleton wallet which I did but Electrum says permission denied and won't import it??  My other question is how do I take the bitcoin stored with Electrum and transfer it to the ColdCard because I think this is the ultimate goal to have offline safe storage?  I'm sorry that I'm not that good technically any help would be greatly appreciated!  I'm working on a Dell computer.
