Hello, pls tell me about redirects

I have this route /legasy?someParam=abracadabra
I should be redirected to actual/abracadabra
the value of the someParam parameter from /legasy?someParam=abracadabra, inserted after actual/

Now with this setup:

{
destination: `actual/:someParam`,
has: [{
type: "query",
key: "someParam",
},],
locale: false,
permanent: true,
source: "/legacy",
},

I have an extra parameter:
/actual/abracadabra?someParam=abracadabra

how resolve this problem?
