Is that safe to connect a USB-C monitor that can charge with 60W AND the Charger at the same time?

Hi,

I recently got my 16 inch MacBook Pro, the computer is super fast but I have one question:

I have a monitor with USB-c at home (LG 27uk850-w) and I like to use it with MacBook when I'm coding,

but 60W from the monitor is not enough to power laptop at load and sometimes battery even go down when it is charging, so I was thinking to hook up the 97W Macbook power supply at the same time to keep battery charged, but I don't dare to do it so I wonder if it's safe to do so?

also, if is it safe to hook up 2 such monitor? in this case how would the charging situation looks like?

Thanks for the help,
