Are XLR Shorting Straps the same as shorting plugs?

I just got a Rowland Model 1 and the manual says to use XLR shorting plugs.  I was also told by an industry rep that I could just use RCA shorting plugs, instead, to short the unused non-inverting inputs, which I’ve done.

I can’t find any XLR shorting plugs but did find XLR shorting strap like this:  https://www.dedicatedaudio.com/collections/adapters/products/cardas-cgsp-xlr-shorting-strap-each

Will this do the same thing as a shorting plug?

Thanks.
