That is because you already have an absurd lots of them though.
I have whatsapp and conversations and that's it. I only use teams on my professional computer, you will never see me install "work" on my personal smartphone and nobody needs a linkedin app, the website is enough.
iMessage is needed for texting, Messenger for neighbours and FB Marketplace, WhatsApp for group chats, and Signal to have a non-meta option.
I agree about LinkedIn and will probably get rid of it; I mostly installed it as I was going to a conference and wanted the easy option for swapping contact details using camera codes.
