Maxmempool

Hey guys

I'm looking to lower my memory pool maximum for my Bitcoin Core node, version 23.0.0.

I would like to lower my max mempool to 100 mb.

Do I need to go into the bitcoin.conf file and add a line that is maxmempool=100 ? or does it need to be in bytes?

I would then save the file and restart core, right?

Please let me know if this is how its supposed to be done, or if this is wrong and I need to do it another way.

Thanks in advance!
