SLACK_USERNAME doesn't overwrite bot name

[bodenloszt]

Hello.

So I used SLACK_USERNAME with GitHub Bot value ( SLACK_USERNAME: "GitHub Bot") but got the Bot name instead:

Shouldn't it overwrite the bot name?

Also, i just observed that the name from the screenshot above it's the name of who merged the PR, not the one who created. Is there any way to remove/edit that?
