Question about the Playfair cipher The task:

The Playfair cipher with $I = J, X$  added into two same letters and
the key keep distance.

The plaintext:

CORONAVIRUS SPREADS FAST


The whitespaces in plaintext and key are to be discarded.

not sure what they mean by I = J, X
The table

I am not quite sure what they are asking for. I know that you usally remove letter J and replace it by I,   But now it says * I = J,X&quot; what does he mean by that?
This is what I've written as &quot;coronavirus spreads fast&quot;
CO RO NA VI RU SX SP RE AD SF AS TX
It means any instances of double letters in encryption are split up by injecting a letter x (as well as the usual I = J).
In other words read the instructions as

I=J
X added into two same letters
Key KEEP DISTANCE
