how to replicate this motion blur effect

Question

I am wondering how to replicate the motion blur effect seen in the image below.

I have tried a variety of approaches: motion blurring the intended word, adding noise and using gradients in layer masks, etc, but all to no avail. I am unsure what to try next. I think my last port of call is going to be trying a gradient map with each colour (pink, purple, red, orange, yellow) being represented somewhere along the black-white continuum. Then, using a soft brush, I could manually paint the blur for each respective colour. But I am unsure if this is going to work and would prefer to enlist some advice before going down this road.
Any thoughts or recommendations are fully welcomed. Thanks for your time.

It is called a "video glitch", more specifically some color offset. Probably you can find some pre-made filter looking for "video Glitch"
(I have not tested it yet) I say that you need to

Separate a copy of the file
Apply a different amount of motion blur to each channel incrementally, let's say 5px for the R 10 for the G 15 for the B.
Apply the reassembled RGB file on top of the original with a blend mode.

Probably you need to apply the same amount of motion blur but offset it for each channel.
I will make some tests later :o)

If we use the logic of the gitch, probably you need to separate the file in YUV channels. But I'm not sure if that is possible on Ps. Probably it can be done in Lab, applying the blur and the offset on the color channels a+b.
