After this command 'sudo -u postgres psql'
I get this message :
could not change directory to "/home/my_account": Permission denied
psql (12.15 (Debian 12.15-1.pgdg120+1))
Type "help" for help.

I tried using help, but to no avail.
What am I doing wrong?

Thanks in advance!

This is normal if you launch psql via "sudo -u postgres" in a directory
that the postgres user doesn't have permissions to read/chdir to.
psql will still start, but its working directory will not be what
you'd expect, so commands that involve local filesystem access might
misbehave.

We have a fix for this error report in the upcoming v16, but psql commands
that involve local filesystem access will still not act very nicely if
psql can't read your directory.

What’s the reason that you’re using the OS user postgres?

If you’re simply trying to connect to the database named postgres as database user postgres, you can instead use the
command'psql -U postgres postgres’.

Because the Debian/Ubuntu packaging sets up pg_hba.conf to use peer auth 
for local connections and the only database user created is postgres.

See:

https://ubuntu.com/server/docs/databases-postgresql

for more information.
