How to pull the argument after the given flags?

Question

Node.js

Good day,
my problem is that I want to pull out a line after the flag,
as it looks like for me:

if(message.content.startsWith("/bug")) { 
        var Author = message.author;
        var Channel = message.channel;
        var title = message.content.split('-t');
        var bug = message.content.split('-p');  
        var embed = new Discord.MessageEmbed() 
           .setTitle("Баг")
           .setColor(RColor) 
           .setAuthor(Author)
           .addFields(
            {name: "Заглавие:", value: `${}`},
            {name: "Баг:", value: `${}`},
            {name: '\u200B', value: '\u200B'},            
            {name: "ПО:\u200B", value: `${}`, inline: true},
            {name: "Лаунчер:\u200B", value: `${}`, inline: true}
            
           )
           .addField("Версия:\u200B", `${title()}`, true)
           
        message.channel.send(embed);
    }

My goal is to create a command in which the specified text between the -t and -p flags would fall into the form and be sent to another discord channel, example command:
/bug -t Some title -p Some problem
It is necessary that the bot put the text after flag '-t' by analogy with '-p'
I know that there are more places for flags than I wrote here, but the main thing for me is to understand how you can pull out the text after the flag.

Well, after I sat for a while and thought, I wrote this code, and it worked:

if (message.content.startsWith("/bug"))
    { 
        var Author = message.author;
        var Channel = message.channel;
        Ttitle = function () {
            const title = message.content.split('-t');
            const Rbug = title[1].split('-b');
            return Rbug[0];
        }
        Tbug = function () {
            const Textbug = message.content.split('-b');
            const RPO = Textbug[1].split('-p');
            return RPO[0];
        }
        TPO = function () {
            const TextPO = message.content.split('-p');
            const Rlauncher = TextPO[1].split('-l');
            return Rlauncher[0];
        }
        Tlauncher = function () {
            const Textlauncher = message.content.split('-l');
            const Rversion = Textlauncher[1].split('-v');
            return Rversion[0];
        }
        TVersion = function () {
            const Textversion = message.content.split('-v');
            return Textversion[1];
        }
        var embed = new Discord.MessageEmbed() 
           .setTitle("Баг")
           .setColor(RColor()) 
           .setAuthor(Author)
           .addFields(
            {name: "Заглавие:", value: `${Ttitle()}`},
            {name: "Баг:", value: `${Tbug()}`},
            {name: '\u200B', value: '\u200B'},            
            {name: "ПО:\u200B", value: `${TPO()}`, inline: true},
            {name: "Лаунчер:\u200B", value: `${Tlauncher()}`, inline: true}
            
           )
           .addField("Версия:\u200B", `${TVersion()}`, true)
           
        message.channel.send(embed);
    }
