Conditional formatting of some words in a long text [regex?]

Hi, I have a custom state, a list, that contains N usernames
The user writes a post into a multiline input and mentions one of the usernames in the custom state by typing @. I’m doing this via a plugin named WGD Mentions. The results is a long text that contains one more “@username”.

I would like such mentions to appear in bold. How can I do it?
Find and Replace cannot be used because I have a list and not an exact text to be replaced.
I suppose I should use Regex but I’m not familiar. It should say “each time you find a word that starts with @, format such word in bold”.

Besides setting the mentions in bold in the output text, is there a way to format the mentions also in the multiline input while I’m typing?

Thanks in advance for your help.

Hello! I recommend taking a look at the following forum posts, where users have solved similar questions:

As noted in the first of these two posts, Bubble doesn’t currently support Regex flags, however you may be able to use one of the workarounds mentioned in these posts.

Hi Rachel I checked those threads but couldn’t solve my problem

I have a text showing

Lorem ipsum #dolor sit amet

and I would like it to be rendered as

Lorem ipsum #dolor sit amet

(I’m using character # as @ here in this forum gets always bolded)

Do you have any suggestion? Thanks in advance.
