How to use the matrix-bot-sdk.LogLevel.INFO function in matrix-bot-sdk

export async function execUnbanCommand(roomId: string, event: any, mjolnir: Mjolnir, parts: string[]) {
    const bits = await parseArguments(roomId, event, mjolnir, parts);
    if (!bits) return; // error already handled

    const ruleContent = {}; // empty == clear/unban
    const stateKey = `rule:${bits.entity}`;

    await mjolnir.client.sendStateEvent(bits.list.roomId, bits.ruleType, stateKey, ruleContent);

    if (USER_RULE_TYPES.includes(bits.ruleType) && parts.length > 5 && parts[5] === 'true') {
        const rule = new MatrixGlob(bits.entity);
        await logMessage(LogLevel.INFO, "UnbanBanCommand", "Unbanning users that match glob: " + bits.entity);
        let unbannedSomeone = false;
        for (const protectedRoomId of Object.keys(mjolnir.protectedRooms)) {
            const members = await mjolnir.client.getRoomMembers(protectedRoomId, null, ['ban'], null);
            for (const member of members) {
                const victim = member['state_key'];
                if (!member['content'] || member['content']['membership'] !== 'ban') continue;
                if (rule.test(victim)) {
                    await logMessage(LogLevel.DEBUG, "UnbanBanCommand", `Unbanning ${victim} in ${protectedRoomId}`);

                    if (!config.noop) {
                        await mjolnir.client.unbanUser(victim, protectedRoomId);
                    } else {
                        await logMessage(LogLevel.WARN, "UnbanBanCommand", `Attempted to unban ${victim} in ${protectedRoomId} but Mjolnir is running in no-op mode`);
                    }

                    unbannedSomeone = true;

}).then(async () => {
            this.currentState = STATE_RUNNING;
            await logMessage(LogLevel.INFO, "Mjolnir@startup", "Startup complete. Now monitoring rooms.");
        });
    }
