Remove period after author in APA style

I want to change the APA style slightly for my thesis in university. I’m fine with everything it does but I would like to eliminate one little thing. For internet sources, I often use a company name or proper noun as the author to reference the source. However, biblatex now also places a period after these, as with the author abbreviations. I believe there should be a way with renewbibmacro* but I know far too little about it to rewrite the macro. Does anyone know a way to omit this dot if there is only one word in the author attribute, as in the example below?

Relevant information:

Example Document:

documentclass[oneside,12pt,toc=bibliography]{srcreprt}
usepackage[english]{babel}
usepackage[backend=biber,style=apa,citestyle=apa]{biblatex}
usepackage[autostyle=true]{csquotes}
addbibresource{bibliographie.bib}
begin{document}
    Here is some text with some quotes.autocite[12]{uml_official}

    printbibliography
end{document}

Example bibliography.bib

@misc{uml_official,
    title = "OMG Unified Modeling Language - Version 2.5.1",
    url = "https://www.omg.org/spec/UML/2.5.1/PDF",
    urldate = "2021-04-28",
    year = "2017",
    author = "{OMG}"
}

What the current bibliography looks like:

OMG. (2017). OMG Unified Modeling Language – Version 2.5.1. […]

What it should look like:

OMG (2017). OMG Unified Modeling Language – Version 2.5.1. […]
