How to get a2m MSA?

I am really new to MSA, would you mind telling me how to get the a2m file that this package required?
Thank you very much.

To create an .a2m file, you can perform a multiple sequence alignment of your protein or nucleotide sequences using a software such as Clustal Omega, MAFFT, or MUSCLE, JALVIEW. These software packages can generate .a2m files directly or can convert the output into the A2M format.
