Remove spaces and create hashtags

I am very new to Make and coding in general.
I have keywords phrases (2 sometimes 3 words in legth) that are seperated by a comma (,). I need to create hashtags for and automated Instagram post, by removing any spaces and the comma and add # to the start of each.

I am stumped on how to proceed further:

Hi John,

there are probably a few different ways of doing this. Here is one. Instead of using Text parser just use replace on its own

This will take a string like

make automation, instagram marketing, social media growth

and convert it to

#makeautomation #instagrammarketing #socialmediagrowth

Brian
