formatting an array of objects output

I have an array of objects that I'm trying to get the output to display properly after using a filter and reduce.

It's outputting the data properly but not in the format I would like. Any input is much appreciated.

CURRENT OUTPUT

{
 5: 12,
 6: 15,
 7: 12,
 ...
}

EXPECTED OUTPUT

{
 session5-count: 12,
 session6-count: 15,
 session7-count: 12,
 ...
}

I'm sure this is something very simple and I haven't had lunch so could be blocking my thought process.

here is my formula and sample data

UPDATED FUNCTION

Thanks to alex-g & zfrisch

const sessionsArray = [
    { session: '5', status: 'inactive' },
    { session: '5', status: 'inactive' },
    { session: '5', status: 'inactive' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '5', status: 'active' },
    { session: '6', status: 'active' },
    { session: '6', status: 'active' },
    { session: '7', status: 'inactive' },
    { session: '7', status: 'inactive' },
    { session: '7', status: 'inactive' },
    ];

const filteredSessions  = sessionsArray
    .reduce( (acc, {session, status}) => {

        if(status != 'active'){
           acc["session-" + session ] = 0
        }else{           
            acc["session-" + session ] =
            acc["session-" + session ] + 1 || 1
        } 
        
        return acc
    }, {}) 

console.log(filteredSessions )

I'm trying to follow along and use THIS S.O. ANSWER to help format my output

You can use template strings to get the desired key format. Like this:

const sessionsArray = [
{ session: '5', status: 'inactive' },
{ session: '5', status: 'inactive' },
{ session: '5', status: 'inactive' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '5', status: 'active' },
{ session: '6', status: 'active' },
{ session: '6', status: 'active' },
{ session: '7', status: 'inactive' },
{ session: '7', status: 'active' },
{ session: '7', status: 'active' },
];

const filteredSessions = sessionsArray
    .filter(workshop => workshop.status === 'active')
    .reduce( (acc, { session }) => {
        
        acc[`session${session}-count`] = acc[`session${session}-count`] + 1 || 1;
        
        return acc;
    }, {});

console.log(filteredSessions)
