I am using Leaflet to work with the map. I have a WMS server: L.tileLayer.wms.

function setWMSLayer(theme) {
    if (!theme.includes("SeaChart_")) theme = "SeaChart_" + theme;
    const url = `http://${FLASK_HOST}/cgi-bin/mapserv?map=/var/www/s57demo/data/map/${theme}.map`;
    wmsLocal.setUrl(url);
    wmsLocal.setParams({
        layers: theme
    });
}

const wmsLocal = L.tileLayer.wms('', {
    noWrap: false
});

Leaflet uses 3857 by default. I want to understand how I can switch the coordinate system. I understand that I can use the proj4.js and proj4leaflet.js plugins. I use them, understand how they work. But I'm not clear on how exactly I can switch my coordinate system. Additionally, I have my .map files, which also have their own projection parameters:

I have read a lot of information on the internet about this, but everywhere the information is different and unclear to me. Can someone help me and explain the most important points so that I understand how I can change the coordinate system? Thanks.
