How Can I import Multibit Private Key into Electrum or Blockchain.com

I am having trouble importing a multibit private key into electrum and blockchaing.com.  The key is declared invalid.

the key looks like this

U2FsdGVkX1+vNknxxxxxxxxxxxxxxU/KiWdlFKlBCv0y613C+rP2t3JMGnuR2xxxxxxxxk/gNe9S
lvv/OJQGbRJ4qP07m3CII4FLvovMg71F8cXSav15QeIxxxxxxxxf

Is this the entire key?
Or
Do I extract segments from the key above? What segment?
