Using apt to remove many packages by mask

Question

I'm new in linux. Trying to remove libreoffice from by xubuntu 20.04. Libreoffice was installed with xubuntu. I execute many variants:

sudo apt remove 'libreoffice\*'
sudo apt remove 'libreoffice*'
sudo apt remove 'libreoffice.*'

In all cases I got error:

E: Unable to locate package libreoffice.*  <result depends on input>

What I tried:

but next solution shows how use apt-get instead of apt.

My questions are:

1. how to specify mask for apt remove command?
2. how to remove correctly libreoffice using apt?
3. what if I use apt-get for this case?
